so I have a TC Compass in 30-06. Every time I shoot it it is absolutely filthy when i get done. I think I finally figured out why. Ran a bore scope down it. it has rough rings of machining marks all the way down the barrel, better in some places but consistent over all. The gun seems to shoot well, it keeps it 1moa claim with my hand loads and me using proper shooting technique. has anyone else seen this?
