lately I've been practicing with my Model 70 in .264 Win Mag, and have been really happy with it's performance at 100 yds (about 2"..dont use a bench or rest at all though so it will probably do better) Im thinking of replacing the 4x scope on it with something a little larger and trying to reach out to about 300 yds. I don't reload, and from what I understand there is not a lot of options to reload the .264 anyways. My question is about barrel fatigue. Everyone tells me that the barrel in that thing is going to burn itself out after a couple thousand rounds. Anyone know anything I can do to prevent that? maybe you know a less-hot brand of ammunition? or should I just keep it as a hunting rifle and use it occasionally? Im a poor college student. Hard enough to buy .264 ammo without having to replace a barrel.
