Not too long ago, I shot .45-70 ammo from the 1880's. A couple of duds, but most fired OK and with no problems.
Just a couple of weeks back, I think it was, I saw a show on the History Channel that discussed Custer and Little Bighorn. They said the .45-70 ammo issued to the troops was copper cased. They said a big part of the jamming problem was that when the copper case obturated, it'd didn't "de-obturate" like a brass case. My question is when did they change to brass cases? IIRC, it wasn't a long time later.
