[QUOTE="Mikecr, post: 730858, member: 1521"] Most answers you get on this subject(anywhere) are flat out wrong -without first defining 'barrel life'. Obviously for some, barrel life holds until bullet jackets separate. For others it's the point where sustained performance passes a peak. Even a 223Rem would not likely see 4000 rounds of 'peak' performance(without having melonite treated the barrel). Competitors who actually shoot precisely(well under 1/2moa) would provide completely different numbers than tactical shooters chasing steel, or hunters who think 1moa is as good as anyone can expect from a hunting gun. Hell, 1moa ain't never gonna be about barrel life... You'd shoot forever before barrel life itself degrades performance that badly. But if your cartridge has truly held 1/4moa, and did so for ~3000 rounds, you'd be real unhappy about 3/8moa at 3500 rounds. Don't matter what others think the barrel life should be for it. You know what it is to you at that point. You know 22-250 and 243 are barrel burners, so they're not ideal for target shooting, which is why you don't see them in competition(as actually competitive). If you want your cake & icing too, you might seek a 6BR or 6.5x47L or 7WSM. Something mild & middle of the road for cal. As mentioned, nothing is free [/QUOTE]
