I'm building a long range rifle for times I don't have to carry it much. I'm ok with a finished weight of up to 12lbs for the rifle only, less is alright too. I want to build a 7mm Rem Mag to shoot the 168gr Berger VLD with a 28" barrel. The action will be a Winchester Classic stainless M70 I have, I'm a big fan of 3 position safeties. Berger recommends a 1 in 10 twist for the barrel. I'm leaning toward a #5 contour at present but open to suggestions. Any advice on what companies barrel I should go with? Thanks for the help. Also I'd appreciate advice on what powders to try with that bullet and the longer barrel to get good consistent velocity and accuracy. Thanks again!
