Agreed. Totally my fault! It is the old haste makes waste that spanked me. My fault.The powerbelts instructions actually discuss the need to monitor crud rings when shooting triple 7. They recommend wet patching bore between shots which I failed to follow. The incredible deal is the accuracy the powerbelts exhibited even out of a barrel that was so severely damaged.
Crud rings don't form 7" from the muzzle.
They form much closer to the breech.
