First, sorry for the terrible picture. I'm no photographer.
Notice the tiny hole and power burn at the edge/corner of the primer pocket at the bottom of the photo.
That is a new, first time fired, Remington 30/06 case. I've loaded, for years, IMR 4064 49.0 grns. I've reloaded factory loaded cases (purchased ammo shot then reloaded cases) since the 70. Some of the cases have been loaded 10 times and nary a problem.
The problem started with the new brass. First, some I had loaded and shot 8 times started blowing holes like pictured. I thought it was because I had uniformed the primer pocket with a RCBS primer pocket tool in my Bench-mate. I dumped those and loaded up some fresh cases. After 5 reloads some started blowing holes. I dumped those and loaded the last 30 new case I had. Two out of the 30 did it on the first firing. Anyone have any idea what's up. It's all going in the trash as I've ordered some new Nosler brass.
They have pitted the hell out of my bolt face and that PO's me to no end.
