I have the Zeiss Victory Diavari 4-16x50_30mm on my 338WM and in summer of 2012 mine was spot on at 93 deg and 500+- ft Elevation in SC at 500 and 600 yds. This year in CO at 40 degrees, 9,000 ft and 402 yds I was able to test my EXL Sheet and scope while laying over my back pack on a log. All 3 were 1" high and at 9, 12 & 3 o-clock. Would have been DRT on any ELK. I seldom ever get to shoot past 100 yd at range.gun)
Which scope and on what rifle are you using?
