I have a Prometheus 407mm inner barrel with a 4/5 cut cylinder...
My field limit is 400FPS so if i add an M120 id imagine my FPS is upwards of 410+ FPS.. (compression is fantastic on this gun right now)
How many teeth would i need to short stroke and what would the resulting Cylinder need be? How exactly do you 'revolume' a cylinder?
NOTE: i have a sorbo pad on the cylinder head as well so already loosing some air volume.
