Typically id consider a synthetic stock on a pre64 anything to be akin to lipstick on a pig but my kiddo has a 257 Ackley improved on a model 70 action. Its a pre war clover leaf and the barrel contour is about a #3. Its got a tiger maple stock that needs inlet and I've got a guy working on it but he's taking his time. Don't really want the kiddo bashing up that pretty wood right out of the gate.
