up for right or left handed use depending on which way you slide in the
assembly.
Installing Locking Pin
The Metering Assembly will dispense up to 250 grains of smokeless powder.
You will notice a tapered hole on the side of the Metering Screw Assembly body,
this is the locking point for the Quick Change Locking Pin. Pull the Locking Pin,
align the hole in the Metering Screw body with the Locking Pin, insert into the
Metering Cylinder and release the Locking Pin. Try to rotate the Metering
Assembly Body to insure that it has been locked in place. Tighten the knurled Pin
Retainer.

The Powder Measure can be mounted on an optional Powder Measure Stand,
available from your reloading dealer. Three friction fit drop tubes are furnished;
one with a small hole for .22 to 270 calibers, and one with a large hole for .30 to
.45 caliber and a very large drop tube for .50 caliber. The QC Funnel Extended
Drop Tube or Adapters also fits for a more precise fit to your cartridge case.

TO USE
Before attempting to throw a series of powder charges, set the powder measure
for the maximum charge and run about a pound of powder through it. This will
deposit a film on the inside of the measure and help the powder flow through
more evenly and consistently.
Be sure you use the same uniform movements for each powder charge. To
throw a charge, raise the handle until it comes to the end of the stroke with a light
tap. Then lower the handle in the same manner. This tap at the end of each
stroke helps to settle the powder uniformly in the measure.
A dependable powder scale should be used to set the first charges in the powder
measure as follows: throw a powder charge directly into the scale pan by raising
the handle and lowering it. Weigh the charge. If it is too heavy, adjust the
measuring screw “in” with the handle in the down position. If the charge is too
light, adjust the measuring screw “out”. When you arrive at the exact charge you
need, lock the metering screw in place with the knurled lock nut on the shaft.
Now you’re ready to throw a series of charges. Additional QC High Capacity
Metering assemblies can be purchased so that you can leave them preset to
your favorite charges, thus allowing for quick powder changeovers.
As a precaution, throw every tenth charge into the scale pan and weigh it to be
sure of consistency.
METERING ASSEMBLY CHANGE
If the same powder is to be used, but you wish to change out the Metering
Assembly for another one that is preset for different charge, it is not necessary to
empty the powder hopper.
Dispense the remaining charge and hold the handle in the “up” position. Loosen
the knurled Lock Pin Retainer, pull the Lock Knob and remove the Metering
Screw Assembly. Align the Lock Pin hole on the side of the Metering Screw
Assembly and insert into the Metering Cylinder, release the Lock Knob. Try to
rotate the Metering Screw Assembly to insure that the Lock Pin is in place.
Tighten the knurled Locking Pin Retainer. As a precaution, dispense a charge
and weigh it to be sure that you have installed the correct preset Metering Screw
Assembly.
CAUTION: If the handle is in the “downposition when the Metering Assembly is
removed, the powder will flow through the Measuring Cylinder and spill out of the
powder measure!
