Running 6.5 hunting loads with 140 class bullets at 3000FPS
(55-60gr powder), barrel life is largely dependent on shooting practices. Shoot long strings in hot weather, I have seen 800-1000 before a .25MOA degradation of accuracy. Keep the barrel less then warm to the touch and keep carbon build up under control, I have seen 1500+ rounds. My smaller cased 6.5 Lapua/CM's(39-42gr powder) in PRS competition /hot weather gets me 2200-2500 rounds….My pet hunting Cooper 6.5x284, 12 years old, and babied, has 1100 rounds through it, no degradation of accuracy, or throat wear….expecting 1500+ out of it.
