This is the 1895 weak weak spot, especially with the 45-70, because of it's large base.
This is what it looks like when it goes. Not mine, photo on line. If one is careful with loads, this won't happen.

That's how flinches are developed.....grin.
I've run some of the Hornady Manual loads for the Marlin through Quickload. The max pressure loads go into the 40K psi pressure range.
I have a JM 1895GBL. My 405gr Load with 40gr RL7 gets over 1500 fps, and predicted pressure is right around 30K psi. That's as far as I care to go with the Marlin 1895.
