I made the switch to BH 209. I'm having serious trouble with blowback in the primer , breech plug. The primer is solid black and I have to pull it out with pliers. I'm shooting a CVA Accura MR , 110 gr powder , Barnes T ez , and Federal 209 A primers ( witch BH recommend ) . Also bought the new BH CVA breech plug . I assume switching primers wI'll fix this problem? Going to try to find some CCI and Winchester.
