[QUOTE="SDMF, post: 195533, member: 412"] OP, I see you've got it, good that you have several resources to choose from. l prefer to do things in MOA, because with 1/4MOA scope adjustments which are fairly standard, I only ever have to "count" to 3. Rifle is zero'd @ 200yds and has a turret that displays each MOA as a whole number: [ATTACH=CONFIG]18814._xfImport[/ATTACH] Now I know my rifle's zero range, my bullet's Ballistic Coefficient (BC), and my load's velocity so I enter that info into a ballistics calculator and print out the corresponding chart: [ATTACH=CONFIG]18815._xfImport[/ATTACH] Let's say that I want to make a 500yd shot. I look at my chart and see that I need 8+2 or 8.5MOA of elevation correction so I spin the turret on my scope to 8 and then count 2 more clicks: [ATTACH=CONFIG]18816._xfImport[/ATTACH] I've just taken the guesswork of "flat-shooting" out of the equation. Now the only guessing I have to do is guessing the wind speed and direction. Now, windage guesswork can be downright confounding because contours of the earth can cause the wind to be present, or not, or funneled and stronger than you can feel. Wind can swirl over or around a hill and really mess with you. That just takes a lot of shooting and observation time to learn, no real way to buy into that knowledge, just gotta learn it through experience. [/QUOTE]
