Tom, I'd just get the standard Kimber MT in 7-08 or 308. Cutting and crowning is usually $35-$45 absolute MAX. My smith charges $35.

Personally, while I love carbines and have owned a pile with 18-21" barrels, I find the Montana "just right" at 22" due to the fact its receiver is shorter than a typical SA rifle.

If I did want one cut, I'd not go below 20" to preserve its balance, and 21" would be great.

Just my opinion...
