If you have an older CVA and have tried to shoot Blackhorn 209 you have likely experienced issues. Blackhorn simply does not ignite reliably in factory CVA breech plugs. It's gotten so bad that they started selling breech plugs specifcally made for Blackhorn 209 powder but only for the V2 Accuras.
So for those of us with an older CVA including the v1 accura we were stuck using the other powders or dealt with ignition issues. I have been trying to find a solution to this problem for quite some time and found that others were modifying their breech plugs for the blackhorn 209 powder. I spoke to Carl here in Laramie and he suggested doing this myself as he did not have time. I did some research and found this thread from a gunsmith in Rapid who has done this many times. If you do a search for ronlaughlin CVA breech plug modification you will find it. I would post it but it might just get deleted by mods.
I copied his simple instructions and it worked out great. Required a 5/32 drill bit, 3/8 82 degree spotting drill, 10/32 tap, and a vent. Took less than 10 minutes. 5/32 all the way through. 3/8 to a depth of 3/8, Tap 8 threads.
