I am looking for a long range bolt action accurate .308. I have heard the best results(withouth spending thousands) are from a .308 with a rem 700 action. Am I better off (if this is the best caliber / action combo for me) buying a rem 700 .308 and modifiying it or buying a .308 700 action in a package for long range shooting? By the way remember somwhat of budget. An also...I understand somewhat the ballistics of a short vs log .30 cartridge as far as burning the powder as far as accuracy is concerned. Sorry for all the "as far as". Any input?
