early small bore black powder cartridges
I have a small collection of early small bore black powder cartridges for short range target and some small game. Once smokeless powder took over these became obsolete, one survivor was the UMC 25-20 which became the wildcat Griffin & Howe 22-3000. G&H even
had cartridges manufactured with their G&H headstamp. The Winchester 25-20 was introduced years later and not included here.

Interesting the 22-3000 is a copper jacketed projectile as I had always tied BP cartridges with lead projectiles some very nice cartridges there RCS
Dug out an old 45/70 WRA Co. Lead projie I really have no idea if its BP or not.

CINDERS, I need to correct my statement in my above posting, the original 25-25 cartridge from 1882 (not related to the later 25-20 Winchester cartridge for lever
actions) was used to develop a wildcat smokeless cartridge around 1934. It was called the 22-3000 R2 (second attempt at chamber reamer hence the R2) and became
quite popular because it fire a 45gr jacket bullet at 3000 fps plus was quite accurate. Griffin & Howe called it the 22-3000 G&H and had cases headstamped with their
name. Winchester also produced cases. Many fine single shot actions were custom made as long range small game hunting rifles, until the 222 Remington appeared in
1950, the 22-3000 was the long range small bore cartridge while the 220 Swift had its followers it was never as popular.
I should have stated the third cartridge (22-3000) with the jacket bullet was a wildcat turned into a proprietory cartridge developed from a black powder cartridge from
1882.
One way to determine if your 45-70 is black power loaded is to get the weight of the complete cartridge, bullet looks like the 405 gr, primed case is about 150 grs
depending on manufacture and see what is left in weight. Black power could be 55 to 70 grs
