Just received a brand new CVA Optima V2 and a brand new Blackhorn 209 breech plug. Went to the range for the first time yesterday. I'm using Federal 209A primers and Blackhorn 209 powder. The primers are coming out black and there is soot on the breech face and the end of the breech plug. I've been researching and I've seen suggestions of putting an o-ring inside the breech plug (does this actually work and will the o-ring stay in the breech plug?) I've read about putting a shim inside the firing pin assembly to move the breech face closer to the primer. Again, does this really work? I checked to see if I was getting any crush on the primers and the answer is no. No crush on .295" Federal 209A's or on .302" Winchester 209's.
As a side note, I also have the older style CVA Optima with a Blackhorn 209 breechplug and it does not have blowback issues and it doesn't get any crush on Federal 209A's but it does get a .001 crush on Winchester 209's.
What do I do? Thank you.
