Do you guys see any problems using the higher pressure loads in a pre-war model 70 (rifle in excellent condition) chambered in 257 roberts? I can't imagine that it would be a problem given the that the pre-war model 70 is a strong action.

Any thoughts?

kynadog,
IMHO, the +p load was for modern guns, that means NOT the 91, 96, etc etc etc.. the model 70 will hold 270 pressures..

Yes, they are fine in pre 64 Win.
