I have a 3200 5 x 15 x 50 on my .300 RUM and haven't had any problems with it. I've shot this rifle a lot because I'm always "fiddling" with my bullets. I do own one Leupold scope, but it isn't a fancy one so there really isn't any comparison. If I ever replace my 3200, it will be with the 4200 series that MR300WM is using. The biggest drawback is their mass. They are a bit bulky.
