I recently traded into a Smith & Wesson Model 1905 (4th Change) chambered in 32-20. It came with 16 loose rounds of similarly-aged, corroded, mixed head-stamp ammo. Having no other 32-20 brass, I pulled the bullets with an inertial puller and de-primed the (probably) corrosive primers, so that I could clean and reload the cases and test fire the gun.
The bullets were 100-gr lubricated lead flat points. Fifteen rounds were head-stamped “REM-UMC 32 WCF” They were loaded with smokeless powder, which appeared to be Bullseye or similar.
One round was head-stamped “PETERS 32-20”. It was loaded with a compressed charge of black powder, which stayed in the case when the bullet was pulled, and had to be dug out with a bamboo skewer. Can anyone tell me when manufacture of Peters black-powder 32-20 ammo was discontinued?
