Sorry forgot to write the factor, just corrected it. I dont pretend to rewrite basic physics ;-) The important thing I wanted to point out is that If a gun goes from 250 FPS to 500 FPS with same ammo it not 2 time more energy, it is 4 times.
Anyway it is better to calculate with the weight used as Thundercactus said. Also having double polish bb is crucial because i've seen difference between different BB.
