So (unless my calculations are crappy crapola) if switching to 0.3 makes you lose roughly 30 fps, you will still gain from 300 to 500 joules at these speeds (including speed decrease), while a 30 fps increase at constant weight will only add 200 joules at 0.2g and 300 joules at 0.3g.

actually theres a slight calculation error in ur formula.
E=.5*m*s^2, where E is in joules, M is in KG, S is m/s
so a .2gram bb is .0002KGs, and at 100m/s = 330fps
E=.5* .0002 * 100*100
E=1 Joule
