I picked up a 7mag used on here about a year ago. It was one of their modified factory Remingtons. It actually shoots very well. It will hold 1/2 to 2/3 moa all day. I have shot a couple 1.5" groups at 350 yards. Not sure if I got a great one, or if they typically shoot this well. FYI, before I ever shot the rifle, I did a bedding job on the B&C stock. This probably helped accuracy, but is a very easy step for most do-it-yourself guys.
Hope this helps.
