[QUOTE="BountyHunter, post: 104445, member: 12"] Barrel mftrs depend on the steel mftr to provide a quality product to work with. Most of the time they have no way to test the steel they get. For example a friend of mine got a barrel from a barrel mftr that had been giving him very good barrels. However, in shooting he suddenly started losing mysteriously one bullet on the way to the target. We finally found an occlusion (pit/hole) that surfaced in the barrel that was not there before. As the barrel heated up it expanded and tore the jacket of the bullet where it disentegrated in mid air. At least that is what we think and he cut down the number of sighters and made it through the season without losing another bullet in mid air. Was this the barrel or steel mftr fault? The barrel scoped clean and 100% when new, but the occlusion must have been just under the surface of the bore. Now is the barrel lands and grooves cut straight? Does the barrel maker lap the muzzle end larger than the bore (if so it will never shoot). Does the barrel maker slug the bore to find high spots, lap them out and then properly mark where you should crown (ie tight spot near muzzle). For all these reasons Broughton is my first choice with Krieger a very close second. BH [/QUOTE]
