I have a Montana in 7/08. I have trouble shooting tight groups off the bench. I don't have good technique, or bags, or even a good bench. It has been easy to hit with in the field however. Elk at 200-250 yards, deer at 300, a coyote at 300, even a squirrel at 75. The only way to truly find out how the rifle works for you is to try it.
My son has a Montana in .243. Off a bipod, it will put 3 Barnes TSX bullets in 5/8" at 100 yards. He's used it on two mule deer bucks, one at 350, and another at 250. In my experience, they are nice little rifles.
