[QUOTE="jlanecr500, post: 5884582, member: 16430"] I threaded a barrel and installed a brake on a rifle several years ago. I was amazed at how much runout the barrel had while holding the breech and muzzle on center. It was a factory sporter barrel and shot well. I had to shoot it afterwards just to see for myself. I was amazed. As to the off center chamber, you would think the chamber reamer was piloted and should have stayed on center. However, some smith's drill/bore the chamber first and ream with a finish reamer. This method leaves a lot of variables on the table. Saving the cost of a piloted rough chamber reamer just isn't worth the chances of ruining a barrel. Also, as land diameter is variable between barrels, reamer pilots should be changed to a diameter that closely matches the land diameter with the appropriate clearance of course. [/QUOTE]
