That bulge at the case head, is it really anything to worry about? It would seem to me that with each firing it would only bulge so far and then the chamber would contain it. It seem's to me that by moving it back every time the case would get weak there. I learned to partial size because I was getting a lot of head split's with my 7mm mag. Stopped it pretty well after going to partial sizing. Had two 338 mag's and never had the problem with them. But then with both of them I partial sized. In partial sizing shouldn't the entire case be re-sized some? Even at the head? Even if you leave the case to rub a bit, I would think it would actually be rubbing full length!
