I'll use my 0.25g when pistol games are pretty intense, say pistols only or CQB type stuff. But for field use, where my G19 is my back up, I might have to shoot through brush, shoot guys that wear thick webbing/vests or even flak vests (for the fit & pockets, not cuz they are pussies) and helps them know they got hit, and for longer range stuff if I feel lucky. Found past 50-60ft 0.25g would veer off in one way or another, not exactly the type of performance you want out of an "Oh crap!!!" gun, so my being a sniper-type have a variety of ammo on hand, found I can hit man sized targets easily and consistantly with 0.30g BBs in my G19 using propane 100ft out. My kinda back up weapon.
