When purchasing Black Powder be certain that it is in the original manufacturer’s
container and that its granulation or type is clearly marked on the label. Follow the stor-
age and handling precautions which are on the label. If you have any questions concern-
ing the safe handling or storage of Black Powder, write to the manufacturer of the pow-
der. Additional information on powder storage is available from the National Fire Protec-
tion Association, P.O. Box 9146, Quincy, Mass. 02269. Or call 1-800-344-3555. Ask for
pamphlet #495.
This instructional booklet lists a range of Black Powder loads which are proper for
your Thompson/Center firearm. Use only the granulation of Black Powder that is listed for
your specific caliber and model. You will note that a series of charges are shown in each
instance. The lightest charge shown for your firearm is the
starting load. The heaviest
charge listed is the maximum load. Start with the lightest load and work upwards gradu-
ally until you reach your best performing load. You will find that the best shooting
load is well below the maximum charge listed.
Never exceed the maximum load listed for your particular firearm. OVER-
LOADS MAY CAUSE DAMAGE TO THE FIREARM AND INJURY AND/OR DEATH TO
THE SHOOTER OR BYSTANDERS AND DAMAGE TO PROPERTY.
Pyrodex is a propellant powder designed for use in muzzleloading cap lock rifles,
pistols and shotguns. Pyrodex is not a Black Powder. In accordance with the manufactur-
er’s instructions, Pyrodex relates closely to Black Powder on a volume to volume basis
(not weight of charge). In other words, a black powder measure set to dispense 70
grains of black powder will, in fact, dispense approximately 52 grains of Pyrodex (by
weight). However, this lighter charge of Pyrodex will provide a charge which is
ballistically similar to 70 grains of Black Powder. For all practical purposes,
knowing the actual weight of a charge of Pyrodex may be informative, but not
necessary. Your black powder measure will dictate the proper amount by its
graduations according to volume. If you want to know the actual comparative weight
of a Pyrodex charge, contact the manufacturer, Hodgdon Powder Co. Inc., Shawnee
Mission, KS. 66201.
Pyrodex does not ignite as easily as Black Powder and, consequently, it is not rec-
ommended for use in flint lock firearms. Flint locks require strong, positive ignition and
should be charged and primed with Black Powder of the appropriate granulation only.
