22WRF I purchased a Winchester model-70 featherweight (one of the first when they brought back the CRF in the early 80s) that shot extremely low and was told I needed to shim the bases. I sent it back to Winchester and they checked the square on the action and barrel and replaced the barrel. It is one of the most accurate rifles I have ever shot. I bedded it to a brown precision stock and it will group inside a dime all day long with good factory ammo and under an inch with cheap stuff. I just know what is right and wrong and something is not right with the Kimber.
