Pierced primers

[Ed Blake]

I've experienced that also with RSTs. I've never had it happen on any other kind of ammo.

I shoot four hammer guns with a variety of ammo. One pierces a lot of primers of any make , two do occassionally, and one never. The only way I know I have pierced a primer is the previously mentioned black center. The gas trapping of the Parker hammer gun is essentially perfect.
