Throw distance values are based on a terminal velocity of 75 FPM (0.38 m/s).
Throw distance values at other terminal velocities may be established by multiplying throw distances in table above by
throw factor:
Terminal Velocity Throw Factor
50 FPM (.25 m/s) x 1.50
100 FPM (.51 m/s) x .75
150 FPM (.76 m/s) x .50
