I've owned 3 Burris' scopes, the first, a palin Jane 3x9 fulfield was great. The last two were both 3 x 10 x 50's and neither could hold a zero on my magnum rifles. I burnt 2 boxes of shells thru my Weatherby before I gave up and took it back. Replaced them both with the Nikon BDC's and have fallen in love with them. Great scopes.
