how concerned are you with barrel life????
I have shot a 300 rem ultra mag and it wallops, but will burn a barrel out in less than 1000 rounds.
My 308 is more accurate and has less than half the recoil. One of the guns has atleast 3000 rounds through it and shows no signs of throat erosion problems.
what do you really want to do with this rifle, and maybe I can give suggestions. Do you want a standard chambering? new wildcat? what size and type of barrel? weight of gun is it a bencher or do you actually plan on carrying it?
I dont want to sound rude or anything but need to know more about your intentions before I can recommend anything.
My favorite 30 is the 308 followed closely by the 300 wsm
, I dont know how barrel life will be with the wsm yet.
