Did you get the CVA "model" breechplug or did you get it directly from Blackhorn (Westrn) Powder??
I guess Blackhorn sells it as a kit with cleaing tools and an "O" ring to help seat the primer.
Can you use the BH 209 Breechplug to shoot other brands loose powder?? I thinbk you can, but can't use it to shoot pellets.
