My experience with the Montana 1999 action and barrel was not good. Had one put in a wonderful Serengeti stock. I just couldn't get the rifle to shoot, I'm talking 1-2" groups. Serengite rebedded the rifle and recrowned it, didn't help. It was a 257Bob. I am currently having it rebarreled by a local smith who told me he'd never seen an action that needed more squaring. My action and barrel were some of the first, like M.D. says maybe they are getting better. I hope so.
