I failed to mention that I clean bottlenecks pockets for 308 and 06 mainly because I pass them through M1a and M1. They are flush and I have noticed slight dimple on some of the primers I didn't detonate. Never had a slam fire and don't want one!!!!! Most of the forum contibutors seem to omit pistol cleaning but reamain steadfast on rifle. I haven't been able to find ss tumbling material via Cheap than dirt, Natcheex, or Midway. Any suggestions?????
