[QUOTE="Kiwi Nate, post: 372043, member: 8533"] I have been through the same problem. Sub MOA with new brass, over 1MOA with fired brass. Turned out that the chamber was not cut concentric to the bore. After re-barreling, the rifle was fine. Also pays to check that the bolt face is square during re-barreling. If you check over all of the other potential problems that guys have suggested and still come up with nothing, it just might be that you have the above chamber problem. The new brass is soft and maleable but on the second firing, it can't form to the error within the chamber, the way it did on the first firing. Its not unusual for a rifle with a poorly cut chamber to shoot sub MOA with new brass or factory ammo. [/QUOTE]
