And not all guns are consistant with delivering the same energy to BBs of different weights.
Case in point, my old KSC USP Compact. It shot 300 fps whether I used .20g or .25g BBs.
Correct and incorrect. An AEG's FPS is directly related to BB weight. Gas guns are not affected as much and retain higher FPS when shooting with heavier weights.
