Sounds like you've done most the work. Get the M150 and give her a whirl. You might find it does exactly what it says on the tin.

If it is a tad over, (like 520fps) then you can afford to cut 1-2coils off at a time. Just make sure you don't cut too much down that your piston goes slack.

:EDIT: Be aware of your joule creep though. If you're using .45's and running with good air seal and close to 500fps... You're gonna get pulled up.
