I use .050" for anything in the 22br. That long neck means no issues with capacity vs bullet placement

Where are 75 AMAX's still available is what I want to know?

Do you know the cbto measurement at touch for a 75 Amax with .050” freebore?

A 75 Amax is the absolute longest/heaviest bullet that I want to shoot in my next build. Everything else will be 50-60 class bullets. I know the long neck helps, but I want to make sure that I can reach the lands with a 50 grain boat tail and not intrude into the powder space with a 75 Amax.

I’ve got about 600 left that I want to shoot in my next build.

I can find out. It's going to be close to 1.850 OAL

That would be great if you don’t mind!! I added a little color in my reply to you as to what I’m trying to accomplish.

Keep in mind it'll work I've built one. But the pressure is a real killer. The bolt you're working with is going to be limited to about 48kpsi. The mag length isn't going to be the issue.
