in general I'm not much interested in powder coating but have a specific situation where it could help me, maybe. I have a carbine with a large bore and a mold that drops a bullet that would likely be the right diameter with PC.
The catch is this carbine has a bore so rough it needs a good coating of lube to shoot cast decently. The rough bore destroys paper patches without that same coat of lube in the barrel. So my question is, will a bore this rough shoot PC bullets ok or will it shred the PC and then lead the crop out of the bore?
