[QUOTE="BrentM, post: 1772004, member: 61747"] Hornady has nice free on line program. Personally I spend a little extra and get an app for the phone, like AB or shooter. They are cheap and you can play around anytime with the phone and run different situations to see the effects of ammo, environment etc. Spin drift is not linear but for your rifle it is about .25 at 500, .6 at 1000 and .7 at 1100. I don't mess with spin drift in the .1 range. For example 500 and less I don't care. 500-1000 I'll consider wind and add .5. 1000-1500 is .75. 1500-2000 is 1 moa. To get rid all this bs I zero .5" left and never mess with spin drift to 1000. [/QUOTE]
