1. I have a CVA Accura MR. I installed the BH209 BP and got the O-rings (couldn't find the shim kit in stock anywhere). I notice that when I shoot primers (without a load) I get a small amount of black smudge up the side of the primer. However, when I shoot a load, the primers come out perfectly clean. Can anyone explain this?
2. How many shots should I be able to shoot without cleaning the BP before experiencing loss of accuracy? Is it possible to only get 5 or 6 good shots before needing to clean the BP flash hole etc.?
