I don't own the kimber, but i have built two rifles with the same stock, the High Tech Specialties. I built a 7mmRM with a Rem700 action and a 260 on commercial Mausers action. Both with Shilen match stainless #3 barrels. The 260 has less recoil. The 7mm bucks the wind. The result is the 7mm is always twice as accurate, because the wind always seems to be twice as important as the recoil.

Flipped him over 4 hooves in the air. Hit him right where I aimed from 477 yards.
