[QUOTE="Broz, post: 815905, member: 7503"] You have something wrong in your settings I would guess. Here are the number I ran for my 300 win. and support as to why I do what I do in reguards to using Coriolis at 1000. Looking at elevation only here at 46* latitude where I live and hunt. A shot with a perfect West 270* azmuth for my 300 win at 1000 yards requires a dial up of[B] 21.4 moa when corolis effect is included[/B]. The shot perfectly East 90* azmuth needs [B]20.9 when coriolis is included.[/B] [B]So .5 moa difference[/B]. This is a worst case scenario shooting dead East or West. So in a [B]worst case scenario I would shoot 2 1/2" high to 2 1/2" low [/B]and I am not sure I could detect why since my rifle shoots 1/2 moa at 1000.[B] If I turn off the coriolis option to the solution the program says 21.2 at 1000. So it would be in error of .2 or .3 of a moa for the two shots.[/B] 1 click at 1000, I only wish I could shoot that consistant.:) Jeff [/QUOTE]
