Black Powder
This is an area I have yet to explore in detail. I'd like to just start off with Winchester's 1895 Catalog #55 and then update later.
After the Civil War manufactures started using the F system to designate black powder granular.
From Winchester's August 1895 catalog
For the 32, 38, and 44 WCF rifles and ALL center-fire pistol cartridges:
American Powder Mills' "Rifle Cartridge, No. 4"
Hazard Powder Company's "Kentucky Rifle F.F.G."
E. I. DuPont. de Nemours & Co.'s "Dupont Rifles F.F.G."
Laflin & Rand Powder Co.'s "Orange Rifle Extra, F.F.G."
For powder to be used in rifle cartridges containing more than 40 grains, we recommend the following brands and sizes of grains as giving the best results:
American Powder Mills' "Rifle Cartridge, No. 3"
Hazard Powder Company's "Kentucky Rifle F.G."
E.I. DuPont. de Nemours & Co.'s "Dupont Rifles F.G."
Laflin & Rand Powder Co.'s "Orange Rifle Extra, F.G."
