[QUOTE="trebark, post: 287415, member: 19172"] One thing you need to do is determine your own definition of a barrel that is 'shot-out'. My definition would be for the barrel to begin to average 50% loss in accuracy compared to when it was at it's best. For instance, if the a rifle shoots .5moa, I would consider the barrel shot-out when it began to shoot .75moa. Does that mean I would replace it? maybe not. I remember an article I ready many years ago in Shooting Times magazine. The author (can't remember who) had a .220Swift with a factory barrel. He shot the gun until it would not consistantly hold 1moa at 100 yards. It took years to get to that point. He then had the barrel removed and sawn in half so that he could examine the bore. To his surprise, the rifling was completely obliterated for more than half of the barrel. Only the last 10" (of a 26" barrel) had rifling. [/QUOTE]
