Why do you want to rechamber? What do you think the .348AI can do that the basic .348 can't?

I was reading P.O.'s book and he states its likely one of the most "improved" cartridges and his data suggest 300+fps gains if i remember correctly. It struck me as not just a 100 fps increase like you may see with others.


300 FPS increase... hmmmm....

My M71 is a family inheritance, and I guess I don't see changes worthwhile... influenced by nothing around here that needs shooting with a .348 anyway. Doubly influenced by if there was, I have a family M70 in .338 WM too. Triply influenced by having a boatload of .348 bullets, 6 different brands/weights/styles I think, so I already have plenty of fodder for handloading experiments, without needing to change the case too.

Good luck with your project!

I looked up what I read. The standard 348 with max load with 4064 of 58gr and 150gr bullet yielded 2835fps. AI chamber with max load of 67 gr 4064 with 150gr bullet was 3175.
The 250gr bullet went from 2150 fps to 2530. pretty substantial difference.
