Re: Primer ? for Triple 7 powder
I had bad crud ring problems with Win, Rem, and CCI primers. I gave up and, having an Omega, got a breech plug made to use 25ACP cases with small rifle primers instead. It works beautifully.
If you have an Omega or Encore it is easy to make your own using the right size drill bit and calipers to get the depth right. I have made a couple since.
