I have had three. I basically moved them on because they are heavier than I like for the kind of deer and elk hunting that I do. I gave my last one, chambered in .300 Win Mag, to my older stepson who has hunted it hard. He is a beast and is hard on his equipment. It has held up better than most of the stuff that he uses, and it is still very accurate with my 165-grain hand loads.
