I keep reading that some calibers are "barrel burners". I can see how a competition shooter would burn a barrel, just as a race driver burns more brakes and tires in a day than I do in several years. How does that relate to me, shooting my 30-06 just enough to be ready for deer season or decompress after a day amongst the hoplophobes? I've taken an interest in the 6.5mm's (6.5-06, 6.5-284, .264 Win.Mag), so am I really looking at having to rebarrel every few years? I tend not to load hot enough to extrude primers in my '06 and I'm pretty sure it will outlive me. Is the whole "barrel burner" thing just a problem for someone who pushes things to the ragged edge?
