A gentleman by the name of Jordan Smith on here has a Kimber Montana 7-08 that was shooting wildly. He had a thread showing that he removed the bedding under the shank which free floated the barrel back to the receiver/lug. This caused him to shoot very well on his next trip out with the same handloads.

I recently did the same on my Kimber Montana 223 that wont shoot heavier bullets as well as I'd like it to. Will report back my results. The next step is to dremel out the bottom of the lug but want to try it as is first.
