Lock-N-Load® Power Case Prep Center
OVERVIEW
Thank you for purchasing the Hornady® Lock-N-Load® Power Case Prep Center. Please read these instructions before using this machine. If
you have any questions about this machine, contact us at 1-800-338-3220.
Product Description:
The Hornady® Lock-N-Load® Power Case Prep Center features a powered Case Trimmer and six work stations for the following reloading tools:
Chamfer Tool, Deburring Tool, large and small Primer Pocket Cleaning Heads and caliber specific case neck brushes. The Power Case Prep Center
may also be used to deburr flash holes and uniform/ream primer pockets with optional accessories which are sold separately.
The Cam-Lock™ feature on the Hornady® Lock-N-Load® Power Case Prep Center locks the case in a removable Shell Holder for precise trimming.
The Lock-N-Load® Power Case Prep Center will only work with Hornady Shell Holders (Hornady Shell Holders are sold separately). The Power Case
Prep Center comes with a 5/64” hex wrench and seven interchangeable pilots to accommodate .22 cal, 6mm, .270 cal, 7mm, .30 cal, .38 cal
and .45 caliber cartridges. Other pilots are available. Caliber specific pilots are used to align the case mouth on the cutting unit. The Hornady®
Lock-N-Load® Power Case Prep Center is engineered to help you significantly improve the efficiency of your reloading process by combining several
essential case prep tools into one unit.
General Information About Case Trimming:
Repeated firing and reloading results in the brass of a case flowing towards the case mouth. Reloaded cases grow in length because of these
actions. When a case exceeds its maximum case length, it may contact the throat of a firearm. If this happens, the case will not release the bullet
properly upon firing and chamber pressure will subsequently increase. Whenever a case grows longer than its maximum specified length it must
be trimmed back to a length near the minimum for that caliber. Trim and maximum case length specifications for modern cartridges are published
in the Hornady Handbook of Cartridge Reloading. (Refer to this handbook for case trim specifications and other case prep topics.)
Safety Precautions:
The Hornady® Lock-N-Load® Power Case Prep Center has been engineered with your safety in mind. The likelihood of an injury or property damage
is reduced when these safety precautions are followed.
• Become thoroughly familiar with the machine by studying these instructions.
• Leave the machine unplugged until you are ready to prep cases and have read these instructions.
• Do not work on or near damp or wet surfaces.
• Plug power cord into a properly grounded outlet.
• Wear eye protection when operating the Power Case Prep Center.
• Do not use this machine if you’re rushed for time and don’t take shortcuts by attempting to bypass any of these instructions.
The Hornady® Lock-N-Load® Power Case Prep Center has an in-line fuse to protect the motor from damage when the cutter is under too much load.
If you try to trim off more than .050” at a time really fast you may put too much load on the motor which will blow the fuse. The fuse is a 1¼ amp,
¼” x 1¼” fast acting glass fuse. You can purchase these at most automotive or electronic stores. Under normal use, you should never have to
replace the fuse. NEVER USE A FUSE LARGER THAN 1¼ AMP.
No-Risk Lifetime Warranty
All Hornady reloading tools and accessories are warranted against material defects and workmanship for the life of the product.
Simply stated – if it breaks, we’ll repair it or replace it at no charge (at Hornady Manufacturing Company’s option).
Instructions for Power
Case Prep Center:
Secure the Hornady® Lock-N-Load® Power Case Prep Center
to your reloading bench with four 1/2" diameter bolts, nuts
and washers. Select a bolt length based on the dimensions of
your reloading bench.
Before you start trimming, make sure all cases have been
full-length sized or neck sized with a reloading die.
Check to make sure the power cord is NOT plugged in.
Insert a caliber specific pilot into the cutter, e.g. use trimmer
1
pilot #1 for .223 Remington. Tighten pilot set screw with the
5/64" hex wrench.
Loosen Main Adjustment Knob on the back of the machine
and turn the Main Adjust Handle counter clockwise so there is
ample room between the Shell Holder and Trimmer Pilot.
When you have installed a caliber specific pilot, focus your
2
attention on the Position Screw which is located on the
right side of the Spindle Platform. The bottom hole is used
to accommodate short/medium cases and the upper hole is
used for long cases. To check the initial position of the Shell
Holder, insert a case into the Shell Holder Retainer and rotate
it counterclockwise to lock up the case. The slot in the Shell
Holder should be facing the front of the machine. If it is not,
pull down the T-Handle approximately 1/2" and unscrew the
Position Screw. Rotate the Spindle Stop clockwise until the
slot in the Shell Holder faces the front of the machine.
Reinstall the Position Screw in the upper or lower hole.
NOTE: You may have to move the Spindle Stop clockwise or
counterclockwise to realign the Position Screw with the upper
or lower hole. Snug the Position Screw once it’s in position.
To remove the Shell Holder, screw the Shell Holder Retainer
clockwise one turn and pull out the Shell Holder.
Turn the Shell Holder Retainer clockwise one turn, pull out
3
the Plunger or the Shell Holder and the Plunger. Insert the
Plunger through the center hole of the Shell Holder. Check to
make sure the O-Ring is between the Plunger and the Shell
Holder.
Replace the Shell Holder and Plunger and screw the Shell
Holder Retainer counterclockwise one turn.

Hornady reloading tools and accessories are warranted against defective materials and workmanship only. This warranty is void if the product
(1) has been damaged by accident or unreasonable use, neglect, improper service or other causes not arising out of defects in material
or workmanship; or (2) has been altered or repairs have been made or attempted by other than authorized factory personnel; (3) is used
commercially; or (4) has been altered or defaced in any way.
This warranty supersedes all other warranties for Hornady products either written or oral. No other warranty is expressed or implied.
Guide a case specific Shell Holder into the Shell Holder
Retainer until it snaps into place, e.g. use Hornady Shell
Holder #16 for .223 Remington.
Turn the Cam-Lock™ handle clockwise until the Plunger is
flush with base of Shell Holder. Insert a case into the Shell
Holder and turn the Cam-Lock™ handle counterclockwise.
This will lock the case in the Shell Holder.
NOTE: Check to make sure the slot in the Shell Holder
Retainer is facing the front of the machine when you lock a
case up in the Shell Holder.

and turn the Main Adjust Handle counterclockwise until the
case mouth is approximately 0.5" above the trimmer pilot
with the T-handle in the up position
Tighten the Main Adjustment Knob and lower the T-handle to
5
determine how much fine adjustment is needed until the case
mouth makes contact with the trimmer cutter.
Loosen the Main Adjustment Knob (approximately a half
turn) and turn the Micro Adjust Handle clockwise or
counterclockwise until the case mouth barely touches the
trimmer cutter.
NOTE: Each mark (knurl) on the Micro Adjust Handle is
equivalent to .001" of vertical adjustment.

primer pocket use the wire brush to remove powder residue
from the case neck. If your cases require trimming then you
will need to use the Chamfer and Deburring Tools. These tools
are easy to use but we feel it would be helpful to cover the
basic techniques.
Grasp a trimmed case and slowly guide the case mouth on to
the point of Chamfer Tool with light pressure. Hold the case
on the Chamfer Tool for approximately five seconds or until
the tool produces a very small bevel on the inner surface of
the case mouth. This will make bullet seating easier.
When you are satisfied with the bevel on the case mouth
remove the burr from the outer surface of the case neck by
guiding the case mouth to the spindle of the Deburring Tool.
Apply light pressure and hold case on the Deburring Tool for
approximately five seconds or until the burrs are removed
from the outer surface of the case neck.

Use the Primer Pocket Cleaner Heads and the Case Neck
Brush to remove accumulated carbon deposits and powder
residue from your cases after every reloading cycle. These
tools are simple to use but we feel it would be helpful to cover
some basic techniques.
To use the Primer Pocket Cleaner Head, grasp a fired case

and guide the primer pocket to the small or large cleaner
head. Use small head for small rifle calibers, e.g. .223
Remington and large head for large rifle calibers, e.g. .243
Winchester. Apply light pressure for approximately five
seconds or until carbon deposits are removed from the primer
pocket. When you are satisfied with the condition of the
