Maybe get a ruling from the experts here. Bought a second hand barrel and have had a very difficult time getting it to shoot. Caliber is known to be easy to find a load for. After about 160-170 rounds trying to get some consistency and seeing some great ES/SD numbers, but practically no good groups. Certainly no consistent performance group wise, a friend loaned me his bore scope. The photos are what I found at the crown. To me, this looks like something I need to rule out before wasting more powder/bullets.
What do you guys think? Re-crown possibly required?
