One should not seek to maximize FPS to the limit.

300 fps is the target... 350 is the limit.

Particularly in places with no mercy and 0 distance engagements... you don't need to be shooting at 350 ..

350 will cause bleeders, 350 will cause welts...

I've seen guns shooing at 320 penetrate skin and lodge the bb below the skin requireing minor "home surgery" to extract.

For indoor play you should be going for 270- 320 basically TM stock
