4.
Rotate the handle 90° toward you to the neutral position, so
that the Thumbscrew and scale are horizontal to the work
surface (at 9
o’clock).
5.
While the Arm is in the neutral position (that is, neither fully
up, filling, nor fully down, dispensing), slowly move the
Charge Bar toward the powder charge until it stops, and lock
in place with the Thumbscrew.
6.
Fully lift up the Charge Arm handle (to 12
o’clock) to allow
the powder charge to flow out through the Drop Tube.
7.
The Charge Arm/Charge Bar should now be adjusted to the
volume of powder corresponding to the sample charge you
weighed into the Powder Measure. Load your powder into
the Hopper and throw a few charges, weighing each one to
verify accuracy. If needed, make slight adjustments with your
Charge Bar to fine tune.
The Charge Arm is now adjusted for a selected volume. Fill the
Hopper and verify the next 2-3 charges by weighing them. If
necessary, adjust the Charge Bar. The Powder Measure is ready
to charge all your cases. You should be able to throw a charge
every 4 seconds.

Tips for Effective, Repeatable Measurement
To get acquainted with your Powder Measure, throw several
charges with a given powder and setting. Check each one
on an accurate scale.
Your hand motion needs to be consistent and deliberate.
Practice by moving the handle with a slow, steady downward
movement. Try this experiment: Throw three charges with a
slow and steady movement through the entire 180° and let
the handle stop firmly. Repeat, but use a swift down
movement of the handle
– this time, you should find the
charge smaller by ½ grain or more.
The Powder Measure will throw up to 95 grains of smokeless
gun powder. For larger charges, set the volume to half the
total and throw two charges.
Some users find a better feel and more consistent handle
throw
by “choking up” on the Arm Casting (010631-015) as
opposed to using the Knob (CT1010-021).
If a coarse grain of powder shears, back up a very small
amount and clear the cutoff.
Visually inspect the cases for unintended double charges by
inspecting them in a loading block.
It is important to remember that charge volumes can vary
from day to day, depending on temperature, humidity, static,
and the type of powder used. For cases of the same caliber,
it is best to verify the powder’s weight and volume in the
empty cartridge, at least at the start
of the day’s handloading

MAINTENANCE
Assure the Locknut (010631-021) stays tight to the Cross
Bolt (010631-026) as the powder should never accumulate
between the machined Powder Measure surfaces.
It is not necessary to remove your Powder Measure from the
bench in order to empty the Hopper (010631-025). Lift the
handle 90°, remove the Charge Bar (010631-024), set the
powder can under the opening in the Handle, and lower the
Handle. Powder will drain from the hopper.
