I apologize if this has been asked already, but when did Kimber go to Bergara and Criterion barrels? I have a .257 Roberts I bought 4 years ago that does 1.5"-3" groups. I got it from Euro Optics and from talking to them it sounded like it was made well before I bought it. It does consistently shoot 1" with Hammer Hunters however. Rebarreling may be the way to go.
