John your correct, but I think it's the throat that gets eroded, it can be avoided by not seating the bullet head so deep amongst other things, but I wouldn't want to shoot that thing 600 times! Thanks for the heads up.NBK said:Not high jacking the thread but here is some interesting info on the 338/378 -
The barrel life of expected decent accuracy is around 600 rounds. After that, barrel erosion takes over. It is a true 1000 yard gun but is somewhat punishing to say the least. I guess anything with over 5000 ft pounds of energy is brutal no doubt.
Below speaks for itself!
Weatherby factory ammo, has a 225gr Barnes TSX moving out at 3180. Holy smokes!
