Instructions

Introduction

Congratulations on your selection of the Frankford Arsenal Super charger™ Powder Measure. The Super charger
Powder Measure is the end result of years of research and development and has been produced under rigid manufac­turing and quality control standards, resulting in one of the finest powder measures available to reloaders today. The
unique angled frame design is engineered to allow the rotor cutting edges to cut cleanly rather than crush individual
powder grains for more consistent powder charges. The Super charger Powder Measure accomplishes this over a
shorter range of motion than many so-called “benchrest” type powder measures in today’s market. In addition, this
unique design incorporates the most desirable powder measure features demanded by today’s advanced reloader. With
reasonable care and periodic cleaning, your new powder measure should provide you with years of dependable ser­vice.

Disclaimer

Since Frankford Arsenal has no control over the choice of reloading components (ie., cases,
bullets, primers, and powder), the manner in which they are assembled, the use of the powder
measure, or the firearms in which the resulting reloaded ammunition may be used, no
responsibility, either expressed or implied, is assumed for the use of ammunition reloaded
with this powder measure.

W a rning

Never use rotary powder measures for dispensing black powder, Pyrodex, or other black powder
substitutes. These powders are sensitive to impact. Operation of the rotor handle will crush black
powder granules between the sharp edges of the steel rotor and the powder measure frame
and can potentially ignite the powder causing all the powder in the powder measure to explode,
resulting in property damage, serious injury, or death.

Mounting and Assembly

Your new Super charger Powder Measure is shipped completely assembled and ready to use with the exception of the
clear drop tube extension and the drop tube nozzles. The powder measure should be mounted securely to a solid shelf
or bench. Rigid mounting of the powder measure is essential for consistent charges, particularly with coarse grained
powders. You should use a well-braced shelf or the edge of a solid bench that is not subject to accidental jarring or
vibration. The shelf or bench top should be rigid and at least 3/4” thick.

Mount and assemble the powder measure as follows.

• Carefully position the shelf mount bracket against the edge of the bench or shelf in a convenient location.
If using the bench mount stand, position the stand so the bend in the base is even with the front edge of the
bench top in order to provide clearance for the clear drop tube extension.

• Mark the position of the mounting holes using a pencil or punch.

• Drill two mounting holes in the edge of the shelf or the bench top using a 1/8” to 9/64” drill bit.

• Secure the powder measure mounting bracket or stand to the shelf or bench with the two #12 Phillips
wood screws (provided) using a #3 Phillips screwdriver.

• If using the bench mount stand, remove the drop tube adapter from the shelf mount bracket using a 1­1/8” box end wrench or socket. Reinstall the drop tube adapter onto the bench mount bracket.

• The powder measure can now be slipped over the drop tube that has been secured to the mounting
bracket or stand. The drop tube adaptor used in conjunction with the mounting bracket or stand allows
for easy removal of the powder measure to change powders or empty, and allows the user to align the

2

measure at any desired angle.

• Secure the powder measure to the drop tube adaptor by tightening the body lock screw.

• Detach the nozzles from the mold trees and slip the pre-lubricated O-rings over the small end of the clear drop
tube extension and each nozzle. Roll the O-rings downward until they snap in place into the O-ring groove
found on each nozzle. Note each nozzle has the caliber size molded into it. Match the caliber size on the
nozzle to that shown on the storage box lid. Insert the completed nozzles (large end pointing downward) into
the appropriate cavity in the storage box.

• Powder measure components are covered in a rust preventative to protect them from corrosion during
shipping. To prevent powder from sticking to these components, this rust preventative must be removed prior
to use. Remove the powder measure from the drop tube adaptor and disassemble the powder measure by
loosening the knurled micrometer lock screw and the rotor/micrometer lock screw. The rotor/micrometer lock
screw requires a 3/32" hex key (provided). Slide the micrometer out of the rotor and slide the rotor out of the
powder measure body. Using isopropyl alcohol (or other suitable degreaser), thoroughly clean the inside of
the drop tube, the outside of the rotor, the rotor cavity, the rotor bearing surfaces, and the top of the rifle
micrometer metering screw. The top of the pistol micrometer metering screw and metering cavity must also be
cleaned with a cotton swap soaked in alcohol. Reinstall the rotor and micrometer as provided in the instructions
below.

Powder Measure Setup and Adjustment

The Super charger Powder Measure dispenses powder by volume rather than by weight. Always use an accurate and
reliable powder scale in conjunction with the powder measure to set the powder measure micrometer for the desired
powder charge weight. Set up and adjust the Super charger Powder Measure as follows:

1. Verify that the powder measure hopper and metering chamber are empty and free from any loose

powder before attempting to use it. If there is powder in the measure and the powder can be identified,
return it to the original factory container. If not, empty into an appropriate container and discard in a safe
manner.

2. Select a proper load combination (powder, powder charge weight, and bullet weight) from reliable

(published) load data.

3. Select and install the correct micrometer (rifle or pistol micrometer) for your specific powder and load.

The rifle or large micrometer is designed for medium to large capacity rifle cartridges that use ball or extruded
powders. The pistol micrometer has a smaller metering chamber designed specifically for pistol and small
capacity rifle cartridges that use ball or flake powders. To remove a micrometer, loosen the micrometer lock
screw (the knurled screw on the micrometer body) and then the rotor/micrometer lock screw (located on the left
side of the rotor). The rotor/micrometer lock screw will require a 3/32” hex key (provided). After loosening the
screw, slide out the existing micrometer.

To install the rifle micrometer, loosen the knurled micrometer lock screw.
Then rotate the micrometer thimble, while holding the micrometer body
stationary, until the micrometer assembly is zeroed (refer to Figure 1).
With the rotor handle positioned parallel to the bench or shelf top, slide
the micrometer into the rotor cavity until the metering screw bottoms
out against the frame. At this point the beveled edge of the micrometer
body should be approximately even with the outside edge of the powder
measure body. The graduated scale on the micrometer body should be
facing upward with the micrometer lock screw positioned to the left.
Tighten the rotor/micrometer lock screw to secure the micrometer. Turn
the micrometer thimble counterclockwise slightly so that no drag is felt
when the rotor is cycled.

Figure 1

To install and zero the pistol micrometer, the micrometer body should be inserted fully into the rotor cavity until

3

it bottoms out against the powder measure frame.

Both the rifle and pistol micrometers are zeroed at the factory. However, if for any reason the micrometers
fail to zero or are ever disassembled, they must be re-zeroed prior to use as follows:

• Loosen the knurled micrometer lock screw and back the micrometer thimble away several turns from the
zero point.

• With the rotor handle lifted to the midpoint of its travel, install the desired micrometer as follows. If using
the pistol micrometer slide the micrometer into the rotor cavity until it bottoms out against the frame. If
using the rifle micrometer, slide the micrometer into the rotor cavity until the beveled edge is
approximately even with the outside edge of the powder measure body.

• Tighten the rotor/micrometer lock screw.

• Screw the micrometer thimble inward (gently) until the metering screw just bottoms out against the
powder measure frame. Tighten the micrometer lock screw.

• Loosen the thimble set screw and reposition the thimble until it is zeroed. Tighten the thimble set screw,
loosen the micrometer lock screw, and screw the thimble outward (counterclockwise) slightly so that the
metering screw does not drag when the rotor is cycled.

• The micrometer is now zeroed.

4. Fill the powder hopper with the proper powder. The powder hopper should be filled well above the top of
the baffle (at least half full).

!

Do not remove or re-orient the hopper baffle. Its location and configuration have

been determined experimentally and have been optimized to provide consistent powder

charges. Removing or re-orienting the baffle will degrade powder measure accuracy.

5. Gently tap the hopper tube with a your finger several times to help settle the powder in the hopper.

6. Select a drop tube nozzle that provides the correct fit for the caliber you are reloading, and insert the
nozzle into the bottom of the drop tube adapter until it comes to a stop. Note the drop tube nozzles fit the
following calibers:

............................................................Use Nozzle

7. If you intend to use the clear drop tube extension, insert the chosen drop tube nozzle in the end of the drop
tube extension instead of the drop tube adapter. Then insert the drop tube extension into the bottom of the
drop tube adapter. NOTE: If you are using the Benchmount stand, you must also use the clear drop tube
extension in order to have sufficient clearance to charge cases from a loading block.

8. Zero your powder scale, then set the powder scale for the desired charge weight.

9. If you have not used the powder measure or the chosen powder before, guess at an initial micrometer
setting or set the powder measure micrometer to approximately the mid-point of its travel. Be sure to
loosen the knurled lock screw prior to setting the micrometer.

10. To throw a powder charge, simply raise and lower the powder measure handle. Operate the powder
measure handle slowly and methodically; cycling it first upward until it comes to a stop, pausing to allow
