[QUOTE="Wolf76, post: 1608533, member: 75779"] My general thought on barrel life is this: Slower powders generate a longer pressure curve - less heat- better life. Velocities under 3K help barrel life a lot. Look at the life of a 308 vs 257 bee. Double base powders add to erosion (rl22....cough) Bullet construction likely plays more of a role in barrel wear than weight. [/QUOTE]
