Gas is a whole other ball game tho, the heavier the BB the longer the gas has to expand behind the bb thus the more energy it can transfer to it. All my pistols love .30's and .36's even tho most of em are in the <350fps range, now the socom gemtec oasis, that thing just needs a bit more hop and it could run .43's probably as far as my bolt action can with a 550fps spring and my gbbr loves .36's and .40's as well and its tuned at conservative 360fps@20°c on a full loaded propane mag (just to keep it safe on hotter days, and due to the juel creep associated with gas guns)
