Instructions for the Ruger “Old Army” Percussion cylinder
This “Old Army” percussion cylinder is intended solely for use with Black Powder.
It should never, under any circumstances, be loaded with any type of
smokeless powder as the result could be damage to the revolver and
injury to the shooter or bystanders. Black Powder is usually classified by powder
grain size, with “Fg” being the largest granulation and “FFFFg” being the
smallest granulation normally available. Any granulation within these gradations
could be used in the “Old Army”; normally, however, “FFFg” is the preferred
grain size. Replica black powder such as Pyrodex may be used, so long as
suggested loading data is strictly adhered to.
The “Old Army” is designed to use a .457” diameter round ball or .454” conical
bullet of pure lead. Bullets of either type can be purchased from your dealer,
ready to use, or can easily be cast at home with a small investment in equipment.
