Re: 300 ultra mag
deerkllr,
I have had a 300UM for about 7 years. It is all stainless which
I think helps a little with the barrel life and I adhere closely to the three rouds and cool theory. If I don't I will end up burning the P*SS out of myself, since the rifle is a sporter and has a rather slender 26" barrel. I just started tracking the number of rounds through my rifles last year when I got serious about long range accuracy but I know how much I shoot. I would put my round count at about 500. Hell, I just got the gun shooting well this year. I would not be overly concerned with the barrel life issue if you are a weekend and hunting season shooter like me. The recoil, powder consumption, etc will limit your shooting for you most likely! Keep the majority of your trigger time dedicated to a more economical round like 243, 308 etc and practice practice practice!
