Estimate The Range Of A Target Using A Scope

Ranging with a scope.


Estimating target range with a rifle scope is relatively simple if the reticle is equipped with mil-dot tick marks on the cross-hairs. If not, you can still determine range with an educated guess of where the mil-dots would be. Keep in mind that scopes equipped with mil-dot reticules are designed to gauge distance in meters. The two elements involved are technique and mathematics. The technique entails measuring the number of mil-dots intervals over your target, and the mathematics encompasses converting that information into a usable range.


Instructions








1. Aim your scope at a target with a known height. For example, a target that is 1 meter tall (just over three feet).








2. Align the scope's horizontal cross-hair with the bottom of your target and count the number of mil-dots to the top of your target. As a matter of technique, it is permissible to align the target base with any mil-dot you choose provided that you can accurately measure the number of mil-dot intervals over your target.


3. Divide the known target height by the number of mil-dot intervals and multiply the answer by one thousand. This equation will give you the range to target in meters. For example if your target is 1 meter tall and is covers four mil-dot intervals then your equation would appear as: 1 ÷ 4 = .25 followed by .25 x 1000 = 250. Your range to target is 250 meters.


4. Refer to your distance conversion guide and convert the results into your preferred units of measurement.
