Looking to build my first precision rifle, and am trying to decide on a caliber. I was origionally going to go with the standard 308, but now I'm not so sure. The rifle is going to be a remy 700. Does the 338 round only come in win mag and remy ultra mag? How's this round compare to a 300 win mag? I'm looking to do shooting anywhere from 300 yards to 1000ish in time. What do you suggest? Hows the price in ammo differ? Plus, forgive my nieveness(sp?), but the 338 will work in a 22-250 action I'm assuming? Thanks.
