I once installed a Laylax 170SP spring into my CA M24 and got it cleared for use at a large game, chronied in at a toasty 585fps w/0.20g.
Funny thing is, I wasn't able to hit a single thing with it all day, even using 0.36g BBs and took shots as close as 170ft away. Too windy, but suspect the BBs overhopped to tehe point of extreme instability.
