We were shooting at a fantastic range in MO, concrete benches, front rests and sandbags. Protected on both side with wind breraks. Stock .30 cal. rifles had little trouble making the shots when dialed in with Nikon's Spot On Ballistic Program. We had loads chronograped, scope height measured and the rest was up tot he shooter. An eye opening experience for a lot of guys who had never used nor wanted to use a Nikon BDC reticle scope.
