DDITIONAL FEATURES OF THE

FORSTER BENCH REST®POWDER MEASURE

You will never get powder grains
between the cut-off faces of the
Bench Rest

®

Powder Measure. If
these faces wear, you need only to
tighten the airplane lock nut on the
cross bolt.

It is not necessary to remove your
Forster Bench Rest

®

Measure from the
bench in order to empty the hopper.
Lift the handle 90°, remove the meter­ing rod, set the powder can under the
opening, and lower the handle. Every
kernel will drain from the hopper.

POWDER

MEASURE

This measure will throw uniform charges from 2 1/2 grains of Bullseye to 95 grains of

4320. No extra drums are needed. The powder hopper is designed to allow a minimal
flow of powder to eliminate variation in charges due to changes in the volume of pow­der contained in the hopper. A small outlet of the hopper becomes its own built-in baf­fle, enabling the powder to enter the measure in a uniform manner. This measure has
been tested and approved by leading experts in the reloading field and has been given
the highest recommendations for accuracy and convenience.

DIRECTIONS FOR BENCH REST®POWDER MEASURE

IMPORTANT — Internal powder-flow channels should be thoroughly cleaned with
a non-petroleum base solvent, then brushed with a dry lubricant such as graphite
for best results. The nut on the cross bolt should be tightened so there is no play

between parts. Drop tubes are to be secured lightly. To set the charge chamber, drop the
charge bar to its lowest position. (Part #50010 has two positions; the lower allows charges
of approximately 2-37 grains, the upper approximately 37-95 grains.) With the handle in
the down position, pour the desired weight from your scale pan into the hopper. Rotate
the handle 90° toward you to the neutral position (X on parts chart) and carefully move
the charge bar onto the powder charge and lock it. If the charges thrown are not correct,
the charge bar may be adjusted visually by moving the vernier scale.

UNIFORMITY OF CHARGES

Uniformity of charges will vary from day to day and are a function of temperature, humid­ity, static and the type of powder used. To get acquainted with your Bench Rest®Measure,
throw several charges with a given powder and setting. Check each one on a scale. Try
this experiment — Throw three charges with a slow, steady movement through the entire
180° and let the handle stop firmly. Repeat, but use a swift down movement of the han­dle. On the latter, you will find the charge will be 1/2 grain or more short. We suggest you
practice by moving the handle with a slow, steady downward movement. Another method
used by some is starting the cycle with the handle in the up position.

We suggest you consider the knurled handle as an ornament and use the entire
charge bar as the handle, setting your index finger against the charge bar just above
the vernier. If a coarse grain of powder shears, back up a very small amount and clear
the cutoff. Check every 10th charge on your scale and visually inspect the cases for
double charges by inspecting them in a loading block.

Do not leave powder in the hopper. To clear the hopper, leave the measure attached

to the bench, rotate the handle 90° toward you, remove the charge bar, drop the arm
downward and drain the powder back into the proper container. This measure will throw
2-95 grains. For larger charges, set the measure for half the total and throw two charges.

DO NOT USE THIS POWDER MEASURE FOR BLACK POWDER.

S

AFETY

Always follow instructions and tables from a reliable reloading handbook to deter­mine proper powders, bullet weights, and primer types. Don’t mix powders. Leave the
experimenting to qualified people who have a ballistics background and equipment to
check their work.

NOTE — The inset shows the screw used to
hold the powder measure stationary when
used on a wood shelf.

NOTE — If you remove the Charge Bar
(-024), be sure to refer to the exploded
drawing when reinstalling it.
