I like my Kimber Montanas in 270 WSM & 7MM WSM.
Those Kimber Montana's weigh less than a M70 Featherweight and their action is better.
Of course the brass problem for the 7mm is not good.
He meant their action is better for Kimber. You know, more advanced design ie easer & less expensive to manufacture.
When MRC started up we were out there in Montana and I stopped in to look at what they had. Then they offered two for the price of one action as a start up offer. That was about 2004.
When the actions came they were so rough in their finish that it would have cost way too much to have them operate and look smooth.
