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.

Damn!
Yeah, for sure...
Picture like that will tend to tighten ones pucker strings...

Your picture does do an excellent job of showing how thin the web is between the barrel threads and the magazine tube on an 1895. That's right where they get the hairline crack.
