1. I know, although it will work in a long action.
2. I know
3. I know

As I said before I know what bolt thrust is and what increased bolt thrust can do. You don't have to keep explaining it to me. I'm not arguing your point. In fact I agree with you. The only thing I don't agree with is 70k psi being enough to damage the rifle. I have no proof of that, I just think if it would that Norma wouldn't load their ammunition to such high pressures. We're beating a dead horse here so I won't reply to this thread anymore.
The brass cartridge case begins to flow at 70,000 psi.

And you wont find a cartridge chamber pressure standard above 65,000 psi.
