One of the reasons the Montana CRF actions got a mixed reception when they first appeared is they were meant as a basic action for gunsmiths, who would do the final finish work and also modified the to feed the particular cartridge they were chambered for.
I have a custom rifle built on one that was modified by a competent gunsmith. It works great and shoots very well. Last year I also tested one of their latest syn-stocked XWR rifles, a .270 that worked perfectly and shot very well. As somebody already noted, the XWR's aren't featherweights, but they function and shoot very well. If I wanted another .300 or .338 magnum, they'd for sure be one of the top rifles on my short list.
