Not trying to hijack, but what load and what velocity did you use for that 160PT in your 7x57? I too have a 7x57 and from what I can read the 7mm/08 loads will work in 7x57 ( I have Mod 70 FWT) in a modern action?
Generally speaking, while using H-4350, my 7X57 loads average 2 grains more powder than in the 7-08 for like bullets.
