What I would like to see is a simulation of the flight distance of spherical projectiles varying in weight from .01-1.0 grams.  I would also like to see the velocity of the projectile be adjustable from 0-600 fps.  I would like to be able to account for variables such as air resistance and humidity.

The intended audience for this simulation is the airsoft community and its intended purpose is to dervive the optimum projectile weight for various velocities and conditions.

Thanks in advance,
Brian Craven
