Is it possible to load the 32-20 pistol ammo using the 20 grains of BP. I have a vintage 32-20 S&W pistol dated at or before the 1900's. Is it possible using new brass with pistol primers with between a 80 to 100 grain lead bullet. Is there any difference between BP in that day compared to BP used today. The 32-20 rifles of that day also used the same ammo I gather. Is the reloading rifle ammo versus pistol ammo the same or different. When reloading the BP CTG's does the bullet compress the BP in the casing similar to reloading shotgun shells or traditional BP rifles when loading from the business end.
