Starting load work on a re-barreled 7mag.
Using new nosler brass. After first firing on the new brass, the shoulder has moved .015" and I still don't think it has fully filled the chamber. I can easily chamber the once fired brass. I'm going to set up my FL bushing sizing die to just neck size it for this next firing.
My question is. How much will the pressure change. I ran a pressure test with the new brass. If the brass is not moving as much the 2nd time around. Will that increase or decrease pressure? I'm going to repeat the test on the next firing. Just curious how close I can start to the max pressure I reached in the first test?
Hopefully that makes sense..
