I have been reading this because I have a Montana (280AI) in route as I write. I far from qualify as an expert as a gunsmith or as a tinkerer. I can however hold my on shooting groups from light rifles from the bench. The one question not ask or answered that I noticed is how quick were the shots fired? I worry more if the rifle will put the first shot on the money rather than group size. My 700 MR (260) will shoot in the .4s if I do my part and don't let it heat up much. If I shoot to quickly between shots it will always string up and right to an inch or more. My first shot on a cold barrel is what puts meat on the table. Longest kill with this rifle has been 407 yards.
Just my opinion
Thanks
Steve
