My M249 shoots 380fps at 1500rpm, and it has for well over a year now. That's high speed and high power, there's no reason to go above the 380 mark using .28g BBs.
I've got an 11.1v LiPo, MOSFET, upgraded wiring, Eagle force EF1300 motor (super torque, good speed too), and I'm running prometheus triple torque gears.
The idea was to put as little resistance on the motor as possible. Running LiPo helps significantly since you're putting higher amperage into the motor, like if I was using NiMH I'd have to use like a 14.4v battery.
Don't use guarder gears, they're crap. Guarder motors are sketchy too.
And IMO you probably shouldn't use prometheus gears if you want really quick trigger response since they're REALLY heavy.
