That is a tough call there! The Winchester is after all a pre 64,and you don't see many Safari grades around either...maybe get a good package deal on the pair? If the Mdl 70 was in 250-3000 caliber I would say that one,the 243's are more common.The Safari might get the edge here though...too bad it's not a belted caliber... go with the 270.Is the pre 64 a feather weight or standard weigh?
