I never could warm up to CZ rifles. Something about them just feels "cheap" to me. The bolt handle and action just don't feel right either and the trigger is awful, set or no set.
Win 70 doesn't win any accuracy comps in my experience, but they feel and look way better to me, plus their bolts are much more solid. I'd go Win 70 any day over a CZ.
Ask gunner how accurate the old pre 64 model 70 375H&H, I sold to him, is. The old, pre 64, 375's are known to be good shooters.
