I'm looking for a good long range setup. I'm interested at shooting 500-700 yards. I know it'll take a lot if practice, and ALOT of knowledge. So my question is, what caliber will be consistent at the distance? I know .308 are pretty stable in flight. I haven't really looked at any of the .338 variations. What caliber, and rifle would be capable of such consistency? Would the rem 700 be able to pull that off? I'm looking for opinions and experience, and this is the place to go I guess. Thanks!
