Kenny , the 30-06 was the most common Chambering , so I would do what you want with it . There is something about the old Model 70 Action which " feels " right to me . If you are going to build a Custom and you can't do some of the work yourself , it gets expensive pretty quick . You have to balance out the cost of the Custom ( and the time and searching around for the Gunsmith (s) ) versus Cash for your M70 and the Cost of something like a Cooper , Sako , etc . BTW , I used to Collect pre 64s and the Chambering in a pre 64 has a whole lot to do with its Value , as does Condition . Try pricing a 9X57 MM or 7.65 MM Pre 64 in any Condition . I have seen both for Sale , and the Prices are astronomical ! You have to be real careful these days because the really Rare Pre 64s ( as well as the boxes and hang tags ) are being faked by guys who know exactly what the real thing looks like.
