Yes, on the bumping the shoulder. I am running into fat cases above the rim. Since I have so much of it, I measured a hundred or so an picked some that were .4422" and under above the rim. They'll chamber and extract mostly but I don't care to have to mortar them out. I do have about 100 of some PPU cases that were once fired and they'll chamber fine but I don't care to use them. The Proof chamber is smaller (at least at the case head area) than the Satern chamber. Both use the .136" bolt FWIW.
New cases should be here no later than Friday and then I can start. I'm not hurting for supplies and have about every bullet available to try from 107-130 grains and 6 different SR primers. I'll try my usual Grendel powders (8208, 2520, and LeverRevolution) and see if the Proof reputation lives for me.
My Satern barreled rifle pushes 107/108's best with 8208 running @ 2675 or so. Favorite bullet for that rifle is a pointed 120 SMK, LeverRevolution, Wolf SRM (or 450's), max mag length @ 2640. This is a 24" barrel.
I typically shoot @ 600 yards off of a very good front rest and rear bag using 22 power and above scopes. I treat them like a bolt gun with some exceptions. These aren't run and gun rifles and I tend to be interested in accuracy above all else.
