I have an old excellent shape Ruger M77 in.35 Whelen. Would it be worth putting a new precision .30'06 barrel in 5R rifling on this action? Would it fit the bill of all the new trendy .308? It sits in a very nice HS Precision stock. FYI: I have a great M1 Garand in 30'06 that it would complement. Basically is the action good enough?
