I get the distinct impression that much of the "barrel life" garbage that floats around is based on conjecture rather than actual experience.

I would trust the word of a long range competitive shooter, since he would likely have a fair idea how many rounds actually were shot through any given barrel before accuracy started to degrade noticeably. To me, unless that throat is gone in under 800 rounds, the issue of barrel life is a moot point. My personal experience leads me to believe that barrels are not as prone to quickly lose "practical" accuracy as many persons think they will. I have shot out several barrels, but it usually took quite a bit more shooting than it was "supposed" to, according to some armchair experts. I had an early production Ruger 77V in
220 Swift. I took meticulous care of it and never shot it in strings that would make it very hot. It was a very accurate rifle, and I noticed accuracy seemed to lose it's "edge" at somewhat over 2500 rounds. By seating the bullets a bit further out, I was able to recapture most of the lost accuracy, and it was at about 3500 rounds that it would no longer maintain MOA. That is a lot of shooting, particularly for a so-called barrel burner like the Swift. A
6mm Remington I had made it to 3750 rounds before it would no longer maintain MOA. I cooked out the throat on a 7mm STW in 1600, and when I sawed the barrel lengthwise, there was little rifling for the first 3" of the throat. It still shot
hunting accuracy, but was definitely not like it had been when fresh. I have owned several
264 Win Mags, which are reputed to be tough on barrels, but none of mine showed any accuracy deterioration at 1000+ rounds. My present one has only 350 through it, and I do not shoot competitively with it, so expect it to last a long while yet. Obviously, a bench rest shooter will notice even a slight loss in accuracy, but I doubt the average guy out in the field would be aware of the loss. I have seen a barrel ruined in under 600 rounds in a hotshot chambering,[
6.5 x 300 Weatherby] but I also know about how this was abused, often shot in long strings that got it so hot that water would "sizzle" if put on the barrel's outside.

I'm convinced that this barrel would have at least doubled it's life if it had received proper care. I have two long range rifles at present, one is chambered
6mm Remington, the other
6.5-284. I expect them to last for 3-4 seasons yet. By that time I'll be itching to try something else anyway!
