This is about what's happening here-Fired brass: Getting into the area of a full charge there was no problematic protruding primers. For me, the brass and primers looked normal. The next small lot that I load will be with this PPU brass neck sized. More on this later
Necks: I was able to pass a bullet through the neck of a fired case. Doing some measuring I came up with a neck thickness of .013 to .015". Personally, any brass that comes out thicker than PPU does not need to be shot in my rifle. Using medium burning powders for the time being. Next up, the hunt will start for PPU bullets. I may try fire forming some 7mm x57 Hornady brass.
This is my first time out with these rifles. I am trying t0 load for the rifle. That means working with the rifle and not from diagrams etc. I am starting to find additional loading data.
