At the casting bench in the sky. RIP Bret.
I'm a fan of steel wool, 4/0. It's what's used on high gloss blues, it's what the guys at the old Coors Shuetzenfests used, it's not goign to harm a barrel anymore than brass/bronze brushes will.
If you're sure there's no fouling in place, then it sounds like it could have taper. Not much you can do about it except lapping. See how it shoots, it may not be a big deal.
