Re: Pin hole in primers

This was brand new brass I only resized it , I did nothing with the flash hole. There were no indications of pressure. The primers are not cratered, easy extraction of cases from the chamber. As far as chrongraphing I haven't got to that yet. The load was under a max load in the manual. checked C.O.L. all was good. According to the specs.
Also the Primers all felt good and snug when I put them in

Thanks for all replies

Re: Pin hole in primers

"Does anyone have any ideas what would cause this to happen?"

Yeah. It's defective primers. The cups are either too thin or too brittle and the pin holes develop at the bend of the skirt to the top of the cap. I had a similar brick of Remington primers to do the same thing years ago. Don't think it's dangerous but those little burn marks on the bolt are unsightly and the smoke in my face was disconcerting. I pulled the bullets, dumped the powder, pushed the bad caps out, replaced them, then reassembled several boxes of ammo. "Oh, bother!", said Poo. And me too.

Hopefully, you can exchange what's left. If the dealer won't take them back, and he may not, contact the maker and expain your problem; they should replace them.

If that won't work, you are stuck, like me. I religated mine to low pressure cartridges; 45-70, 30-30 and .35 Rem. They do fine for that.

Those were my suspicions but I wanted a confirmation on this, Thanks a bunch Boomtube. At least the primers didn't me cost anything.
