[QUOTE="BountyHunter, post: 1118427, member: 12"] What is interesting out of this thread is two things. 1. Slugging barrels works. Bill Calfee a world renownd 22 LR BR smith wrote a series of articles on this several years ago and was noted for cutting the crown of his barrels at the tight spot regardless of lengths most of the time. It really started the BR community and gunsmiths talking and looking at this with great results. 2. I have never met or talked to a barrel manufacturer that recommended or would warranty a barrel IF someone else had hand lapped it. Barrel mftrs have guys that are artisans that do this and even they know it takes a lot of barrels to learn it. Also, almost all barrel mftrs mark/cut the blank about 1" back at the muzzle, because the best guys in the world that do this know that lapping will normally bell the muzzle a little bit and this is where you lose accuracy. A rookie lapping will run more barrels than they fix. There was a run of bad steel in the mid 2000s that got a lot of barrel mftrs, and I knew several competitors that bought up several blanks to store when they finally hit some quality runs of steel.
