Recently purchased a Smith Carbine Pietta. I have discovered a burr on top of one of the lands. When I slugged the barrel from breech to muzzle i knew it wasn't correct. So I slugged another part way from muzzle down and then drove it back out, no issues. I put a bore scope down it and sure looks like it, I could feel the camera catch on it also.
Wondering what the best method is to remove beside bore paste and elbow grease.
