I have Peterson 375 Chey brass and after 1 firing and completely clean primer pocket I get a shallow seating. This happens about every 40 rounds give or take. Primer sets just past brass bottom but is noticeable when you set it on a level surface upright. It causes changes in my ES/SD which is to be expected. Any thoughts on this? No matter how clean I get primer pocket, primer bottoms out but not when brass new.
