I was hanging out with a buddy the other day and we were discussing blow back around the breech plug.

He said to put a small O ring in the primer pocket to seal it.
I did some research and found a place to get specific O rings for this.

Anyone ever try it or have first hand experience?

I buy them thru McMaster-Carr. They don't last too long but they are cheap. They do stop the blowback.
