Federal PowerShoks, I don't think I have had it happen with my reloads , mind you it does crater the primer
a bit I am using Winchester brass , 24.8 gns of Benchmark 8208 , CCi 400 primers and Sierra 55gn SuperRoos
This rifle is getting around the 1200 rd mark , so I don't think its a great deal to worry about ?
Different primer might be a bit harder?
Funny that it is doing it with factory ammo but those two brands are moving pretty well.
I can't see the rifle or the case so I am only guessing really, cratering can be a worry if the rest of the primer is flat. Worst issue if it is commonplace is pitting on the boltface or danger to your health, the gases are meant to go out the end of the muzzle.
BR4 benchrest CCI primers eliminated my initial primer problems in my .223 for an extra $2 per 100, but was band aiding th problem really. Bushing the bolt eliminated them totally, is it worth it in your case? You are the judge of that but I am wary of exhaust gases even in a stoutly contructed Howa.
Personally I am rather fond of my eyes and always wear safety glasses in case of ruptured primers and cases etc but then I am not your mother.
Good luck and let us know how you go. I am interested.
