Sir;
Sounds like you have a tight chamber. Also, you could have a rough, sharp, entry-way. I'd take a brass rod, slit it and put some 240 grit around it and polish out you chamber just slightly. Then just ever so slightly use a slim countersink with some 240 around it and JUST BREAK THE CHAMBER EDGE. Not too much for this is what backs up the rim when the firing pin strikes.
