BAM. this is where it's at. People should be chronoing with the weight they will be shooting and muzzle energy should be calculated from that.

It's WAY too easy to cheat a chrono if you know how the gearbox and air voluming works.

You could build a gearbox that would chrono 400fps with .2s which is 1.48J but with a .4 it might chrono something that's 1.7 or 1.8J... I pulled those numbers out of my ass, but it's possible to get higher J with heavier ammo with a setup that gets proper fps/J with a .2
I futz with V2s, V3s and V6s. I could be wrong... but probably, most likely not, as far as I know.
