Finished Shotshell Dimensions

Wad Guide/Swing Arm

Assembly

#16802 - 12 gauge shown

Here are some dimensions of a typical 12ga. shotshell. Always use a quality dial caliper when measuring your shotshells. Length may vary dependent upon shotshell manufacturer. Dimensions shown are for maximum, uncrimped overall length. If you find it necessary to adjust the collet size die, try to shoot for a middle of the road measure of t

he brass base.

Wad Seated Depth

When developing loads for shotshells be aware of your “wad seated depth.” Here’s a reference guide for the popular wad and shot weight used presently.

Example, if your loads currently use a wad for 1 1/8 oz. of shot and you decide to reduce your shot weight and switch to 7/8 of an ounce wads, readjust the shot dispenser tube via the body collar adjustment screw. Clockwise rotation raises the shot dispenser tube and decreases the depth the wad is seated into the shotshell. Counterclockwise rotation lowers the shot dispenser tube and the wad will get seated deeper into the shotshell.

Finished Round Information

Your loaded round length will vary due to loads used, type of wads, and brand of shotshells.

We found that a majority of the Winchester ammo loaded fell toward 2.30 - 2.325 length.

The Remington and Federal ammo loaded measured 2.33 -

2.350 overall length.

Always use a reputable loading manual when reloading shotshells.

Reloading ammunition and handling powder and primers is inherently dangerous. Just as in shooting, accidents do happen. These accidents are n

ondiscriminatory; they happen to both the novice and

he experienced reloader.

e have done everything we know how to make your machine as safe as possible. We cannot, however, guarantee your complete safety. To minimize your risk, use common sense when reloading and follow these basic rules:

Never operate the machine without ear and eye protection on. Call our customer service department at (

800) 223-4570 for information on the wide variety of

hooting/safety glasses and hearing protection that

Dillon has to offer.

• PAY ATTENTION: Load only when you can give your complete attention to the loading process. Don’t watch television or try to carry on a conversation and load at the same time. Watch the automatic systems operate and make sure they are functioning properly. If you are interrupted or must leave and come back to your loading, always inspect the hulls at every station to insure that the proper operations have been completed.

• SMOKING: Do not smoke while reloading or allow anyone else to smoke in your reloading area. Do not allow open flames in reloading area.

• SAFETY DEVICES: Do not remove any safety devices from your machine or modify your machine in any way.

• MODIFICATIONS: Any modifications performed to a machine, or the addition of any unapproved equipment from other manufacturers will void the warranty.

• LEAD WARNING: Be sure to have proper ventilation while handling lead components or when shooting lead bullets. Lead is known to cause birth defects, other reproductive harm and cancer. Wash your hands thoroughly after handling anything made of lead.

• LOADS AND LENGTHS: Avoid maximum loads and pressures at all times. Use only recommended loads from manuals and information supplied by reliable component manufacturers and suppliers. Since Dillon Precision has no control over the components which may be used on their equipment, no responsibility is implied or assumed for results obtained through the use of any such components.

Refer to a reliable loading manual for overall length (OAL).

• QUALITY CHECKS: Every 50-100 rounds, perform periodic quality control checks on the ammunition being produced. Check the amount of powder being dropped and primer supply.

• RELOADING

AREA: Keep your components safely stored. Clear your work area of loose powder, primers and other flammables before loading.

• COMPONENTS: Never have more than one type of powder in your reloading area at a time. The risk of a mix-up is too great. Keep powder containers closed.

Be sure to inspect hulls prior to reloading for flaws,

cracks, splits or defects. Throw these hulls away.

Keep components and ammunition out of reach of

children.

• WINCHESTER HULLS: Please be aware that Winchester has redesigned the AA target hull. This hull is no longer a one-piece extruded design. Now, it is a two-piece hull incorporating an inner reinforcing tube

which extends partway up the interior of the hull.

Winchester wads have been redesigned to work with this new design. Additionally, some after-market wads a

re now available which are compatible with the

edesigned hulls. Other wads may not be compatible

ith the new AA hulls.

We suggest that you visually inspect your hulls, and load the old and new style hulls separately, using components appropriate to each style of hull.

• BLACK POWDER: Do not use black powder or black powder substitutes in any Dillon powder measure. Loading black powder cartridges requires specialized l

oading equipment and techniques. Failure to do so can

esult in severe injury or death.

• PRIMERS: Never force primers. If they get stuck in the operation of the machine, disassemble it and gently remove the obstruction.

Never attempt to deprime live primers – eventually one will go off. When it does it will detonate the others in the spent primer cup. Depriming live primers is the single most dangerous thing you can do in reloading and can cause grave injury or death.

• LOADED AMMUNITION: Properly label all of your loaded ammunition (Date, Type of wad, primer, powder, shot charge, etc.).

• BE PATIENT: Our loading equipment is conservatively rated and you should have no trouble achieving the published rates with a smooth, steady hand. If something doesn’t seem right, stop, look and listen. If the problem or the solution isn’t obvious, call us. The reloading bench is no place to get into a hurry.

• REMEMBER: If your machine does not perform to your expectations, or if you are having technical difficulties, give us a call: (800) 223-4570 or see our troubleshooting page online at www.dillonprecision.com

General Machine Information

Based on our XL 650 machine frame, the SL 900

comes to you with some great automated features.

Starting from the right rear of the mac

hine, the SL 900 features an electric casefeeder. This unit holds approximately 80 empty hulls; enough for three boxes of shotshells.

Turn the electric casefeeder on and the shotshell disc (#17133) will rotate until the feed tube has filled, then the microswitch will shut the unit off. Every stroke of the roller handle (#22183) transfers one empty hull from the feed tube to the shellplate via the case insert slide ramp. Once a hull has been placed in station one of the machine, moving the roller handle (#22183) down will resize the brass base of the hull, expand the mouth of the hull and remo

e the old

primer.

NOTE: Always examine the hulls for rocks, dirt, mud or other cases that may get stuck inside. Also look for hulls that ma

y appear stepped on or flattened. Go ahead and squeeze them round again so they won’t get stuck in the casefeed tube (#20536). Returning the roller handle (#22183) to its full aft position will advance the hull to station two, where a new primer is inserted into the hull when you push the roller handle (#22183) aft.

MANDATORY SAFETY MEASURES

SL 900, May 2007 5/21/07 11:51 AM Page 16

The automatic primer system holds 100 shotshell primers. Every complete stroke of the roller handle (#22183) will feed a primer to the hull.

The automatic powder system is also located at station two. The hopper holds one half pound of powder and has a fully adjustable powder bar. The automatic powder system is hull activated. Move the roller handle (#22183) do

wn. When the hull contacts the expander/powder funnel (#16746), the powder measure is pushed up, causing the po

wder bar to

e and dispense one c

harge of po

wder into the hull. Raise the roller handle (#22183) to its rest position. The powder bar will recharge and the hull will ad

ance to station three.

At the third station (left, front of the machine) we will insert the wad and meter the shot into the shell. Move the roller handle (#22183) aft as if you are seating a primer into the hull. You will see the wad swing arm (#16677) tilt out, ready to accept a new wad. With every complete stroke of the roller handle (#22183), insert a new wad into the wad swing arm (#16677) when it tilts out.

e the roller handle (#22183) do

wn. T

he shot drop tube (#16726) inserts the new wad into the empty hull and will dispense shot into the hull. Raise the roller handle (#22183) and push aft to prime. Hold the handle aft while you insert a wad into the swing arm.

At station four we start the crimp in the top of the loaded hull. It is formed and folded closed, preparing the hull for the final crimp and seating performed in station five.

The formed, folded top of the hull will now be crimped and seated closed. This die is fully adjustable. The crimp and seating depth can be adjusted to the desired settings.

This die also has a taper crimp feature inside that will form a tapered end to the hull. Again, move the roller handle (#22183) down and then back up to its rest position. T

he completed shotshell advances out of the machine, down the shotshell chute (#16672) and into the Dillon bin (#17125).

Step by Step Preliminary Assembly

1. Fasten the strong mounts (#16065) to the base

of the machine while it is lying on its side.

securely to the forward edge of the bench.

Fig. 3

3. Install the casefeed post (#17123) and the shot post (#17124) to the frame of the machine using the two long 4 1/2" bolts, 6 clamps (#13613), 2 - 1/4" washers and 1/4-20 nuts.

Fig. 4

4. Locate the shot container and place it on its post.

Fig. 5

5. Open the casefeeder box. Place the feeder on your bench and plug it into a 110v AC outlet (220v for European casefeeders). Place a handful of empty hulls into the casefeeder (approximately 10). Turn the unit on and familiarize yourself with its operation. Notice how every time an empty hull exits the casefeeder, it passes a microswitch. Later in the loading process, you will see that every time the hull is next to the microswitch the motor will shut off.

Fig. 6

6. Place the casefeeder on its post. Find the clear feed tube and place the bottom of the tube into the 12 Ga. casefeed sleeve (#17130). Align the casefeeder on the post with the clear feed tube and snap the feed tube into its recei

ver. Snug the 1/4-20 screw on the rear of the casefeeder to secure the position of the casefeeder. Please do not fill the clear feed tube with empty hulls. This step will be completed later.

Be sure to secure the small, but important, screw located at the rear of the bowl at the base. This little screw (#13685) secures the entire bowl assembly to the casefeed post (17123).

Fig. 8

7. The powder measure (#17817) is the next item we’ll be installing on the machine. Familiarize yourself with its operation – every complete stroke of the powder bar dispenses one charge of powder. The dispenser is hull activated.

Using a 7/16” wrenc

h, rotate the bolt located on the end of the powder bar – counterclockwise will reduce the po

8. Remove the blue cap on the powder die (#16744). Loosen the two Allen screws and place the powder measure (#17817) on the powder die (#16744). The clamp must lock into the groove of the

die, then secure the tw

o Allen screws firmly

ig. 10

9. Locate the parts bag for your machine. Enclosed is a powder bar return rod (#17350)

Fig. 11. The powder bar return rod (#17350) must be inserted into the bellcrank from its left side. On the bottom of the rod is a blue wing nut (#13799), spring and white rod bushing (#18086). Slide this end into the receiver (

easure (#17817) at this time. This will be completed

later.

10. Next we move to station three where the wad is seated and the shot is dispensed. The Dillon shot dispenser works similar to the powder measure (#17817). The shot dispenser is activated by the hull at this station. No hull – no shot. Every complete stroke of the shot bar dispenses one charge of shot. T

o adjust, loosen the bolt set screw (#16740) 1/4 of a turn. T

hen use a 7/16” wrench to rotate the bolt located on the end of the shot bar (#16738) – counterclockwise will reduce the shot weight and clockwise will increase the shot weight.

Fig. 12

11. To complete the assembly of the shot

dispenser tube, y

ou’ll need the follo

wing items from the parts bag: shot bar return rod (#16733), clear shot feed tube, two shot dispenser fittings (#17139), two shot fitting e-clips (#17202) and tw

o tube clamps.

ig.

12. Assemble the shot dispenser fittings to the

clear shot feed tube.

Fig. 14 Place the tube clamps loosely on the tube. Slide one end of the shot dispenser fitting into the bottom of the shot hopper (#16724

item A Fig. 13) and lock it in using one of the shot fitting e-clips. Now, align the complete assembly and install the other shot dispenser fitting and e-clip into the dispenser top (#17142) and tighten the clamps.

The SL 900 shotshell machine has been assembled and tested using Winchester AA hulls. A sample is included with the machine.

Station One – The collet sizer is adjusted for resizing the brass base.

Fig. 20

Station Two – Inside the powder die (#16744) you’ll find the powder funnel

Fig 21. This part

uniforms the top of the shotshell hull and dispenses one charge of powder into the hull. The powder bar will need to be adjusted to the desired powder weight. Its important to use a quality po

wder scale to

do this. Fig 21A

The powder die has been adjusted to a height so that the powder measure bellcrank can make full strokes when activated.

Before you charge ahead and begin tossing components into your new SL 900 shotshell machine, there is a routine we’d like you to follow.

1. Fill the powder hopper with the powder of your

choice.

Fig. 26 2. You will need a once-fired shotshell

with a spent primer.

Fig. 27 3. You will need a

powder scale to weigh the powder charges.

Fig. 28

4. Place the hull in station two where the powder measure (#17817) is located. Gently move the station two locator (#16694) away from the shellplate and insert the hull.

Fig. 29

5. Move the roller handle (#22183) down and then back to its rest position. Remove the hull from the shellplate by pressing down on the locator button (#16753) and pour the powder back into the clear powder hopper.

Fig. 30

6. Repeat steps 4 and 5 a minimum of four times so you are receiving a uniform powder charge.

7. Weigh the fifth powder charge. Using a 7/16” wrench, rotate the bolt located on the end of the powder bar. Counterclockwise will reduce the powder charge weight. Clockwise will increase the

powder charge weight. Adjust as needed.

8. Again, repeat steps 4 and 5 until you’re happy

with the powder charge.

Now that you have determined the powder charge, let’s go on to station three for wad and shot insertion. Let’s use the same hull, with powder, in station three.

1. Get a supply of w

Its alw

ys easier to make adjustments when the bar is empty and in the forward drop position.

7. Again, repeat steps 4 and 5 until you’re happy with the shot charge. Remember to place the clear hopper lid (#17138) back onto the shot dispenser & tighten the bolt set screw (#16740).

Now that you have determined the shot charge, let’s move on to station four and five where the starter crimp die (#10640) and final seat/crimp functions are performed. Let’s use the same hull (with shot).

1. Place the hull (with shot) into station four.

2. Move the roller handle (#22183) down and then back to its rest position. The formed and folded hull has just completed station four and has advanced to station five.

Note that every complete stroke of the roller handle (#22183) will feed one primer into the machine while at the same time completing the other processes within the machine.

Lets Begin Making a Few Rounds

If you’re like me, you have already figured out that when you cycle the roller handle (#22183), hulls feed into the shellplate and primers also feed into the machine. Let’s begin making a few rounds and I’ll explain the loading process, using the first hull as our guide.

1. With all the stations empty, move the roller

handle (#22183) down and then back up to its full aft position. A hull has been fed into the shellplate.

Fig.

2. Push the roller handle (#22183) aft, away from you. Doing so inserts the hull fully into the shellplate and the first primer appears at station two. Remove this primer and set it aside.

Fig. 46

3. Move the roller handle (#22183) down. The first hull is being resized and the old primer has been removed from the hull.

4. Return the roller handle (#22183) to its rest position. The first hull advances to station two and another hull has been fed to the shellplate.

. Move the roller handle (#22183) down. The first

hull is getting a charge of powder at station two.

7. Return the roller handle (#22183) to its rest position. The first hull advances to station three, another fired hull is fed to the shellplate and the hull at station two is ready to receive a new primer.

Fig. 49

8. Push the roller handle (#22183) to its full aft stop and hold as (using your left hand) you pick up a plastic wad and place it into the wad guide (#16681). This same aft stroke seated the new primer into the hull at station two and the hull at station one is fully seated into the shellplate. Release the roller handle (#22183).

round.

WHEN OPERATING THE ROLLER HANDLE:

Pay close attention to the hulls, noting the changes that take place as they go through the machine. Pace yourself when operating this machine. Do not crash the roller handle (#22183) down against its stops. Do n

ot snatch the roller handle (#22183) upward. It should take two or more seconds to move the roller handle (#22183) from its rest position, down, and then back to its rest position.

Changes and Adjustments

Whenever you plan to make some changes or adjustments to your SL 900 machine, it’s important to have all the right tools.

are needed when adjusting the 12 Ga. collet sizer die (#16743). A 3/16” Allen wrench and a dial caliper. Loosen the die lock bolt (#17351) located in the bottom of the toolhead (#16667).

Fig. 57

Using a fired hull, measure the diameter of the brass base. Place the hull into the machine’s shellplate at station one and resize the hull. Remove the hull from the machine and again measure the diameter. The brass base should be .804 diameter.

Fig.

See page 17 for shotshell dimensions.

To make the brass base smaller, turn the die clockwise using one-quarter turn increments. Using another fired hull to test the new setting, resize the hull in the machine. Again, measure the diameter of the brass base. When you’re finished, tighten the die lock bolt (#17351)

2. Powder Die/Funnel Adjustments – When a powder charge is dropped into a hull, it is very important that the bell crank also makes a complete stroke simultaneously.

Fig 59 Turning the powder die

(#16744) clockwise lowers the powder system and increases the stroke of the bellcrank. Be careful not to go down too far or you may crush a hull. Turning the powder die (#16744) counterclockwise will raise the p

owder system, reducing the amount of stroke the

bellcrank has.

Fig. 60

3. Adjusting the Automatic Powder System Powder Charge Weight

– Place a hull at station two and cycle the handle. Weigh the powder charge from the hull and write that weight down. Using a 7/16” wrench, rotate the bolt located on the end of the powder bar. Fig. 61 Counterclockwise will reduce the powder charge weight, adjust as needed. Helpful hint: oper

ate the powder bar a minimum of four times so you are assured of a uniform po

wder charge, then weigh the

fifth charge.

4. Adjusting the W

ad and Shot Station

– Shot c

harge weight adjustments: Weigh the shot charge from a hull and write that weight down. Refer to your loading manual to decide w

hether y

ou need to increase or decrease the shot charge weight. Using a 7/16” wrench, rotate the bolt on the shot bar (#16738) cloc

kwise to increase the weight or counter

clockwise

to reduce the weight. Adjust as needed.

when it was built and adjusted at the factory. If you have selected a wad that uses a lighter or heavier load of shot, you’ll need to readjust the position of the shot dispenser. Using a 5/32” Allen wrench, loosen the t

wo screws on the collar guide/clamp (#16737).

ig.

A 3/16” Allen wrench is used to rotate the body

collar adjustment screw (#10641).

When reloading with

light shot load plastic wads

it may be necessary to adjust the shot dispenser position. Rotate the body collar adjustment screw (#10641) clockwise to raise the shot dispenser. Tighten all the collar screws, then test the changes.

Fig. 63

When reloading with heavy shot load plastic wads it may be necessary to adjust the shot dispenser position. Rotate the body collar adjustment screw (#10641) counterclockwise to lower the shot dispenser

. Tighten all the screws, then test the

changes.

5. Adjusting the starter crimp Die – This die has been adjusted at the factory using Winchester AA hulls. If you have another brand of hull you’d like to reload, it may be necessary to readjust this die. Test run a hull through the machine to decide if any changes are needed.

What we like to see is a 60% closure of the top, formed and folded. T

his is important so that station

e’

s final crimp/seat can produce a uniform folded

crimp.

Fig. 64

We found that when we reloaded Remington hulls and wads, we would need to adjust the starter crimp die (#10640) down. The heavier walled Remington hulls appear to be somewhat more resistant to being f

ormed and folded. Turn the starter crimp die (#10640) down approximately one-half turn clockwise as needed.

Reloading with Federal hulls and wads requires a little readjusting as well. Raise the starter crimp die (#10640) approximately one-half turn counterclockwise. This will help produce a uniform folded crimp/seat.

Winchester hulls and Versatile wads loaded fine and required little or no adjustment at all. Remington hulls and Versatile wads also loaded fine. Remington hulls and Figure 8 wads require adjustment. The stiffer style Figure 8 wad needs to be compressed; do so by lowering the wad seated depth 1 to 2 full turns (as detailed under step 4 of Changes and Adjustments). Also, reducing the shot charge weight may be necessary when using this wad. Follow the above changes with a readjustment of the starter crimp die (#10640), turn the die down approximately one-half turn clockwise as needed (as detailed under step 5 of Changes and Adjustments).

6. Adjusting the final crimp Die – Two adjustments are available here on the final crimp die. Example, if some of the reloads you have just finished appear shallow as shown, then turn the seat plug clockwise (down), using 1/4 turn increments.

Or, you can turn the whole die clockwise (down) using 1/4 turn increments. You will then see the next reload with more taper on its end and the seated depth will be deeper.

Another example relating to the final crimp die adjustment when reloading different shotshells: “When I have made some reloads, some of the shotshells have buckled in the middle, but it doesn’t happen all the time.” You will need to raise the whole die b

y turning the assembly counterclockwise (up) at

least 1/4 to 1/2 a turn.

When it’s time to switch to another shot size, place a plastic container or coffee can next to the shot dispenser drain. Rotate the plastic shot drain with your index finger and hold it there until all the shot h

as emptied. Any remaining shot in the shot bar (#16738) and dispenser can be removed by running a hull through the machine.

Fig. 65

Example: you’ve just finished making some rounds using #9 lead shot, the next size you’ll be using is #7 1/2 lead shot. Remember to always weigh the shot charge when doing this switch. Please use a quality scale.

Fig. 66

Removing the Toolhead:

One of the great features on a Dillon machine is the removable toolhead (#16667). The removable toolhead (#16667) allows you to convert from one hull brand to another hull brand or another caliber in a matter of minutes. Let’s use the following steps to remove and install a toolhead (#16667) on the SL 900 machine.

1. Empty all the shot from the shot hopper

(#16724) and clear tube via the shot dr

ain.

2. Remove the shot fitting e-clip and the shot

fitting from the shot dispenser top (#17142).

it onto the frame.

8. Insert the two toolhead pins (#14008) into the

holes located on the front and rear of the frame.

9. Install the powder bar return rod (#17350).

10. Install the shot bar return rod (#16733).

11. Attach the shot fitting to the shot dispenser top

(#17142).

12. Install the shot fitting e-clip.

You’ve now completed the toolhead swap – the only step that remains is refilling the components (powder and shot) and you’re ready to go again.

Shellplate Removal

When you service your SL 900 machine – cleaning, lubing, or switching to another caliber – please follow these steps to remove the shellplate.

1. Remove the ejector wire (#16676). Using a small, flat blade screwdriver, hook it beneath the ejector wire (#16676) and lift upw

ard to remove it.

Fig. 71

2. Move the roller handle (#22183) halfway down its stroke.

3. Use a 1/8” Allen wrenc

h to loosen the 1/4-28

brass tip set screw (#13923) located on the left side of the machine, below the platform, in the mainshaft (#13485).

Fig. 72

4. Return the roller handle (#22183) to its rest

position.

5. Use a 1/4” Allen wrench to unscrew the

shellplate bolt (#13418).

6. Remove the shellplate from the machine. Fig.

Be careful not to lose the 3/8” index ball (#13891) and index pawl (#13667) when cleaning and lubing your machine.

The Primer System:

The primer feed system on the SL 900 machine is a fully mechanical system. Every complete stroke of the roller handle (#22183) will feed a new shotshell primer into the machine.

Fig. 80 Two very important

but simple points:

#1. Always keep the machine and its primer feed system clean and free of dirt. Do not place any oils or grease on the primer feed plate. This hinders the free flowing oper

ation of the system.

#2. Never allow excess powder or dirt to build up on the deck where the primer transfer arm (#16691) swings in and out of the machine.

If you decide to service your machine or don’t

wish to ha

ve any primers feeding, install the “stop block” into the primer system as shown. When you’re ready to resume, simply remove the “stop block” and the primers will begin feeding again the next time you cycle the handle.

Troubleshooting Section #1, Primer System

1. I broke my primer transfer arm (#16691). This happens when a new primer is only partially seated into the shotshell. A spare is included with the machine, but

it’s important that you make complete, full strokes of the operating handle when using the SL 900. See Illustrations 1 & 2

2. A

primer is laying sideways inside the clear

cover of the primer tray. How do I remove it?

Shotshell Primers are steel – get a small magnet, screw-driver or pointer and use it to get that primer out. Dillon also provides a magnetic pick-up wand (#22292) as an accessory for the SL900.

Another method available is to simply unscrew the black knobs that secure the cover, slide the clear cover off, and remove all the primers. Reassemble the parts, then refill the primer tray with primers.

From time to time I notice that a new primer lands on the platform rather than into the hole in the primer transfer arm. Why?

Two things may be occurring here: First, the speed in which you operate the handle affects the feeding of new primers. As the new primer is dispensed from the primer tray, it takes a fraction of a second to fall through the tube and into the hole in the primer transfer arm. When you reach the bottom of the handle’s stroke, pause for a second, then move the handle again. Always pace yourself when operating your machine.

Second, you always get a new primer with every complete stroke of the machine’s handle. If there isn’t a shotshell in station two to receive the primer, that primer will be left on the platform.

4. A dirty primer tray can be annoying. If you reload in a dusty environment (for instance, a barn or garage) or the shotshells you have are dirty, over time dust will collect on the primer tray. We've made the primer tray stainless steel so you can clean it with windex or alcohol. Just remove the clear cover and wipe it clean. Our machine cover was designed to help keep your loader clean when you're not using it. Ask for part #13329.

Where does the grease go again? See page 37 in the manual, also make sure your hands are greasefree w

hen handling new primers; they don't feed well in any machine when they’re greasy.

How do I stop the primers from feeding? A rectangular insert has been included with the machine. Place your thumb on the primer drop tube and raise the primer system by pushing it up. Insert the stop block BETWEEN the primer feed body and the tray mounting bracket. Remove the stop block when you're ready to begin reloading again.

When I oper

ate the mac

hine, it doesn’

t alw

ays

drop a primer.

An adjustment screw (#17639, see the schematic on page 13) is located in the platform. This screw increases or reduces the stroke of the blac

primer slide located on the primer tray via the primer drop tube. If the primer moves over the hole but it does not drop thru, turn the adjustment screw counterclockwise to raise the primer drop tube and the black primer slide will stroke more and then the p

rimer will drop thru the hole.

The adjustment screw (#17639) may periodically go out of adjustment. Remove the screw and clean the threads and the hole in the platform with alcohol. Apply some blue Loctite to the threads and reinstall.

Why do I get high primers when using Winchester primers and Remington hulls, but not when using Remington hulls and primers?

The new silver colored Winchester primers appear to be .002 diameter larger than the previous copper colored primers at the point just above the flange. We suggest using a bit more forward push on the operating handle when seating the primer or switching to Remington primers for Remington hulls.

Assure yourself that the primer is fully seated into the shotshell. We’ve found that the primer tr

When the shotshells appear out of the bottom of the dies, remove the suspect shotshell from the priming station. Once you have

Troubleshooting Section #2, Casefeeder

1. General casefeeder information: Capacity is 80 shotshells. Electric motor information: 110V AC for US customers and 220V AC (3 RPM) for European customers.

he shotshells jam in the clear funnel. Always

check the shotshells to make sure that no flattened or stepped on shotshells get into the casefeeder. Suggestion: Use the clear feed tube to gauge any shotshell to make sure that it can slide through the tube before placing it in the casefeeder bowl.

It looks like half of a shotshell is hanging out of

the bottom of the casefeed body.

A shotshell can jam in the casefeed body if the mouth of the shotshell is so deformed that it gets stuck on the casefeed phish inside the casefeed body. Simply remove the shotshell by pulling it out.

I have noticed that the microswitch does not

shut the motor off.

The microswitch uses the pressure of the shotshell against the aluminum arm on the switch to turn the motor off. You can bend the aluminum arm as needed to assure that the switch is activated.

Troubleshooting Section #3, General

1. It’s important that you make complete, full

strokes of the operating handle w

hen using the SL

900.

2. Never use any solvent-type lubricants such as Brakefree or WD-40. These will cause the mainshaft to seize in the main bore.

3. When I operate the machine, some shotshells get stuc

k and strike the mouth of the sizing die.

he shotshells may have a deformed rim or base. Throw the bad shotshells away.

Another possible cause is that a shot pellet may have fallen into the pocket area, stopping the shotshell from feeding in to the shellplate. Inspect the shellplate grooves for any smashed shot or other debris.

The operating handle stopped halfway through

its stroke.

he first thing to do when this occurs is to

tap ev

ery shotshell. See if y

ou can feel w

hic

h one is in a bind. It may be that the primer is not fully seated into the shotshell.

It’

s important that you make

complete, full strokes of the oper

ating handle w

hen

using the SL 900.

It may be that the first shotshell has struck the mouth of the sizing die, or a wad or smaller gauge shotshell is stuck inside the first shotshell and has jammed itself onto the depriming pin. Or it may be t

hat a wad has not entered the shotshell properly and

is caught on the mouth of the shotshell.

Whatever the cause, remove the suspect round by lowering the shotshells out of the dies, then remove the problem round from the machine.

I’m not sure if the powder charge is correct.

Always use a reputable loading manual. The powder bar does not come set from the factory. You must use a scale to adjust the weight of the powder charge being dispensed. The machine manual has detailed instructions on how to set up the powder measure.

When I use the machine some of the wad petals

get caught and fold beneath the shot tube.

Then a spill might occur because the shot is too high in the shotshell. Always inspect the wads before you place them into the wad seater. You can use your thumb to press the petals open, then insert the wad into the wad seater.

How do I remove that last amount of shot from

the shot bar?

When all the shot has been drained out of the large hopper, place a plastic container or coffee can next to the shot dispenser drain. Rotate the plastic shot drain with your index finger and hold it there until all the shot has emptied. Any remaining shot in the shot bar (#16738) and dispenser can be removed by running a hull through the machine.

When I cycle the handle the wad swing arm hits

the edge of the toolhead as it tries to go thru the hole.

We have placed an adjustment set screw below the foot of the wad swing arm inside the platform (#13789, see the schematic on page 10). Using a 1/8” Allen wrench turn the screw as needed to center the wad swing arm in the hole it passes thru in the toolhead.

9. The shot dispenser and the powder systems use

a 10-32 thread kep nut (#13817). T

hese nuts ma

y become loose over time and should be replaced with Nylock nuts (#13841).

10. T

he shot dispensing tube (#17479) is designed to flex during operation. Do not shorten the tube for an

y reason or it will no longer function as it w

designed to.

Two adjustments are available here on the final crimp die. Example, if some of the reloads you have just finished appear shallow as shown here (also on page 17 of the manual), then turn the seat plug clockwise (down), using 1/4 turn increments.

Or, you can turn the whole die clockwise (down) using 1/4 turn increments. You will then see the next reload with more taper on its end and the seated depth will be deeper.

Here are some helpful adjustment settings for the SL 900 Shotshell Loader. These settings illustrate ideal adjustments for the starter crimp and the final crimp die. These settings can also be used to reset these dies if you get completely out of adjustment.
