The kid in CT that murdered his own mother, stole her guns and killed all the students was dropping half-full mags and reloading. IIRC, law enforcement interpreted this behavior as mirroring his FPS “training”. That would seem to indicate capacity didn’t matter as much as simply having a detachable mag. The guy that shot up that Batman theater in CO or wherever brought in a 50 or 100 rnd drum mag (IIRC) and had it jam on him (as they do).
