[QUOTE="Jerry M, post: 1690036, member: 6330"] My 7 mm RM lasted 1,600 rounds; Barrel: Remington 40X heavy (pig) contour 6.5 Remington Magnum lasted 2,200 rounds; Barrel: Shaw Remington Varmint Contour 6.5-06 lasted 1,792 Barrel: Kreigher light Palma Contour .308 Win lasted 6,002 Barrel: Kreigher heavy (pig) Contour Lots of variables to consider. I shot the crap out of these barrels, contuning to shoot most past their accuracy life and pulled them when the: 7mm RM started blowing up SMK at 200 yards; 6.5 Remington Magnum not stay on an 8.5X11 target at 200 yards; 6.5-06 started blowing up SMK at 600 yards (shot another 100 Nosler partitions at 100 yards for grins & giggles because i had them) .308 Win when it would not hold the 8 ring at 600 yards (F-Class). Some of these went from 2 inches to nothing within the last 50 rounds. Others were more gradual. However, I have a buddy that will pull a barrel if it goes from .2 to .5 inch groups. So there is what do you consider 'shot-out'. Good luck Jerry [/QUOTE]
