TO REMOVE A CYLINDER
To remove a measuring cylinder for cleaning, first empty the powder hopper
using the previously described operation. Then pull the Lock Pin and remove the
Drain Tube. You can then either remove the two handle screws and handle or the
Lock Pin Assembly and carefully slide out the measuring cylinder.
Do not attempt to remove the powder hopper from the main casting.
STORAGE
Due to the corrosive nature of Black Powder, the Black Powder Measure must
be disassembled, cleaned and lubricated for storage after each use. Consequently,
the Black Powder Measure must be cleaned to remove the storage lubrication prior
to each use. Failure to follow these instructions will cause the metal parts to
corrode, corrosion is NOT covered by the lifetime warranty.

GENERAL INFORMATION
The Black Powder Measure will perform two powder charging tasks in one fast,
simple operation. Cycling of the handle will accurately measure powder within a
fraction of a grain and swiftly dispense it into a case, one after another. Powder
pours uniformly from the powder hopper into the measuring cylinder, through the
drop tube and into the case. You can change from one charge to another quickly and
easily by adjusting the brass metering screw.
The powder level is visible at all times due to the low powder follower rod
which ‘rides’ the powder stack down.
The measuring cylinder has a precision-machined surface and slides into the
honed main casting for a precise fit. The lower portion of the main casting has the
standard 7/8”-14 threads and may be used on an optional Powder
Measure/Piggyback Stand or Advanced Powder Measure Stand.
A powder measure is basically a device which measures powder by volume and
not by weight. However, before you start throwing a given charge with this powder
measure, the first charges must always be weighed on a powder scale to arrive at the
desired charge. Accurate powder measure charges will also depend upon the size
and uniformity of the powder kernels used, and how smoothly and uniformly you
operate the powder measure handle. For consistency, it is imperative that you follow
a set routine when throwing charges of powder.
Due to the corrosive nature of Black Powder, the Black Powder Measure must
be disassembled, cleaned and lubricated for storage after each use.
TO ASSEMBLE
To prepare the Black Powder Measure for use, the measuring cylinder,
measuring screw, drain attachment, inside of main casting and powder funnel
portion of main casting must be cleaned to remove the factory applied rust
preventative. Failure to do so will cause inconsistent powder charges.
