[QUOTE="HappyWarrior, post: 1964873, member: 115064"] In my safe was an old Remington 722 in 244 carrying a BalVar 8 in Stith mounts. At an auction i bought 10 boxes of factory 244/6mm Rem ammo, so I dusted the old girl off. She shot well with light bullets. About then I bought a Lyman bore scope that revealed the bore still had a lot of machining marks and a few pits. Bought a fire lapping kit from Brownells and started out with the 400 and 800 grits. Things got better (see pics) with 95 gr Hornady factory ammo but scope still showed problems. Back to range today with 220. Worst case I have an as new 243 AI barrel on the shelf.
