[QUOTE="Mikecr, post: 2800775, member: 1521"] For one, there is a big difference between [U]barrel life[/U] and [U]accurate barrel life[/U]. Second, barrel life is not affected by speed of powder burn, but temperature of powder burn. This, along with how much powder is actually burning in the bore, and shot rate, and pressure. It could generally be assumed that a higher % of faster burning powder will burn in the bore. And faster powders typically burn hotter. But neither is a certainty. N133 is very fast AND very cool burning. But, competitive 6PPC shooters who use N133 only get ~900rnds of accurate barrel life -because of competitive pressure loads and rate of fire. If you used a 6PPC for coyote hunting, with reasonable hunting loads,, you could get ~3000rnds of accurate barrel life. And even past that, the gun might still be accurate enough for that hunting at 5,000rnds. Bullets don't matter, as hunting barrels don't 'wear out'. They burn out. [/QUOTE]
