After shooting numerous bottles of Blackhorn, ive never seen the flash hole clog. It actually grows slightly with every shot.
Flash channel, yes....Flash hole...no
The Omega plug and Kodiak plug are more different than they appear. The Omega plug with the heavily concaved powder side is excellent with BLackhorn. As far as i know, they will not interchange.
Ron on Huntingnet and Modern Muzzleloader forums can modify the old style CVA breach plug for excellent reliability. He even installs a vent liner so your plug will basically never wear out. Just replace the vent liner when the flash hole has grown too much.
