inside primed .45/70
A friend showed me a .45/70 case he found at an old army base that was 'inside' primed (looks like a rimfire case). any idea about when these were made/used

very early ,one of the first 45/70 1870's era

Look up Benet internal priming. That may be what you have.

Benet primed rounds were the first 45-70, starting in 1873. They had no headstamps. Stamps began in 1877. In Aug 1882 they changed to an external primer. These were NOT the present day primer design, but used a folded head cartridge case.

Great read, thanks for posting. Here I always thought the 45-70-500 was the original load.

The .45-70 military loads were originally inside primed. The firing pin dented the soft copper case head to fire the charge. The soft copper cases often had extraction problems so the change was made to brass which was too hard to fire inside priming so a separate primer pocket was used as it still is today. An interesting note is that the ammo used in Custer's Little Bighorn fight was inside primed hence all the stories of extraction problems during the battle. Battle field pickups of fired cases are from the several reenactments that were done accounting for all the centerfire cases and their locations in areas where Custer never was.
