Well, Not to offend Leuplod fans, but the Vari-XIII 3.5-10 X 50 mounted on my HS Precison 300 Win Mag, in Warn Mounts, will not hold up to the recoil. It's been back to Leupold twice. To their credit it has been fixed both times at no charge. I recently remounted the scope on the rifle and after several shots, the scope loses point of aim. In my opinion, Leupold has as much a failure rate as other brands on heavy recoiling guns. Leupold optics are great, but there's more to a scope than the quality of the optics. Will I get another Leupold scope, you bet, but not for heavy recoiling guns like the 300 Win Mag.
My 2 cents.
