The OP likely isn't pulling an M150 (or an M170) I doubt that he's really firing that hot. Lower 400 FPS I could see (if using .20's) but likely the FPS has been quoted using .12's.
If it was measured using .12's then at 400-500 FPS on .12's you're only looking at around 320ish-390ish on .20's.
That's quite possible. If that's the case then the speed result is pretty much exactly what to aim for, for outdoor games. No alterations necessary.
