Thread: Long range shooting techniques

Sometimes it is the scope adjustment that is out rather than the ballistic program. You need to check that 1 click = 0.25 MOA or what ever your adjustments are. The usual way to do it is to clamp the rifle and scope sight at a target at 100 yds then move 40 clicks/10MOA the scope should move 10.47 inches. (1 MOA is 1.047" at 100 yds). If it moves more or less you will need to calculate what the click value is. Inches moved / 40clicks/1.047 will give MOA per click. Most ballistic programs allow you to enter click value.

Otherwise fudge muzzle velocity or BC to match actual drops, based on the further the better. ie get it as close as possible for the furtherst range you expect to shoot. If it is a bit off closer in it won't be out by as much. 1 MOA at 300 yds is 3" but 8" at 800 yds. So being 1MOA out at 300 yds will be 3" off but 0.5MOA at 800 yds will be 4" off.
