About six months later, I began to think about my other .30 caliber rifles - .308 match gun and .300 Win Mag hunting rifle. Tried this bullet in both of them. In both instances, I was able to generally use 125 grain powder charges and get 125 grain velocities. Once I heard about the barrel life issue, immediately suspended testing these OX bullets.

The customer with the .30-378 wouldn't switch for all the tea in China. As you mentioned, he only shoots a few rounds each year - a couple to confirm zero (which does not seem to change) and a couple on game. He has taken three elk so far with the gun - two of them at around 300 yards and one at 600. The 600 yard shot was made by holding on the backline of the animal . . .
