Great news. I have a Marlin 1895 SBL 45/70 so maybe I can just use it with shortened cases? However it seems to me that since the 45/70 is a tapered case when it is shortened the inside neck diameter would be too large to properly hold a 0.458" bullet.
Tmitch, please enlighten me. Are you simply firing these shortened cases in your standard 45/70? If so does it feed ok? What bullets are you using? What reloading dies are you using?
Can you provide any load data with velocity?
