Danger Space Stock or upgraded airsoft guns don't have the circular capability of an accurized sniping rifle. The best method to snipe in airsoft or paintball is to find the maximum danger space of your gun. The Danger Space is the distance your round is equal to the top of the target and travels downrange toward impact with the ground. (not taking into account the wind or slant angle). In other words the round will hit somewhere between the top and the bottom of the target as long as it is in the danger space. Airsoft Ballistics Airsoft rounds barely curve upwards (if the hop is adjusted properly) so there is no chance of the maximum ordinate being above the height of your target therefore the round will not pass above the target. Calculating Danger Space The danger space starts the instant the round leaves the barrel. Don't forget airsoft rounds hardly curve upwards. Now here is a technique for calculating your maximum line of sight engagement range. - Find flat land and mark off every 10 feet past the maximum range you can engage targets using line of sight. - Find the point where your round loses it's velocity and hits the ground. - Place a target measuring 30 inches in height (most targets only expose a small portion of their bodies during a game.) at the rounds point of impact on the gound. - Go to your shooting position using your scope look downrange at the target you setup. Since it is at your maximum engagement range it should look small in your scope. - If the target fills your sight picture then you are using too high of a scope magnification for airsoft sniping. Since no mil-dot reticle scopes are available for airsoft sniping I've come up with an acceptable solution for airsoft sniping. Using that target as referance calculate roughly how many times you could fit a target of that size between the middle of the crosshair and the top of your scope. By sizing up the target in your scope you can now calculate if the target is within your rifles danger space. For example: In my scope if a 30 inch target takes up half the space between the top of the scope and the crosshairs I know it is out of range. Any target of roughly 30 inches larger then that is within my acceptable line of sight engagement range (not taking into account wind and slant angle). Once you've spent a few minutes figuring this out write your formula down and memorize it. While scanning for targets it will take you a split second to know if you can engage a target or not regardless of the range. Once you've mastered this technique with a 30 inch target you might want to consider recalculating for a target the size of a persons head (since most heads are roughly the same size). After you've done this when you spot an individual just by sizing up his head in your scope you know if he is too far or within range. Do not go for head shots. Use the head as a range referance only. This technique works for short distance sniping. It allows you to engage targets without having to range them. Field Application - Acquire target through visual sighting with the naked eye or binoculars. - Size up the target in your scope and determine if he is within your danger space. - Adjust for wind and slant angle. - Engage target(s). This technique allows an experienced shooter to rapidly engage multiple targets.
