I am just starting to try this long range shooting and I have 3 different Cal. rifles which I am going to just pick one to use for 6-800yd shots and I just needed some opions on which would be best to start putting money into. I have a Rem.700 in .308,Rem.700 in .270wsm, and a Ruger M77 in 7mm Mag. any help on which one to pick would be appc. I will be hunting Wtail deer but mostly just shooting for fun.
