    How To make an airsoft mortar

    So the basics of ballistics, is that in a standard situation, with no extra wind, or extreme amounts of humidity, then 45 degrees is the angle at which your furthest your shot will go. So, what I did, is I set up a sight with a piece of laminated paper, and a thin piece of steel that connects to the barrel, and lines up with the angle, and has the distance written underneath. I then have a target altitude knob that changes the barrel angle in minute increments in that changes with the target altitude in relation to the launch altitude. For instance, at 160 ft., and my target is ten feet above my position, then my first angle should be at 37 degrees, but my altitude angle is at .01. This means that my overall angle is 37.0122 degrees to the ground. I also have a small telescopic sig...see more »So the basics of ballistics, is that in a standard situation, with no extra wind, or extreme amounts of humidity, then 45 degrees is the angle at which your furthest your shot will go.

This means that my overall angle is 37.0122 degrees to the ground. I also have a small telescopic sight that allows me to view my target at long ranges, and estimate the range based on a small knob inside the sight that shows me two things. My elevation in relation to my target, and the estimated ranges of objects 25, and 45 yards away. With these, I put some decimals into a calculator, and voila! I have my range. In total, it takes me approximately 45 seconds to complete the entire set of requirements in order to hit the target within 10 feet.
