Bah, I've been shot with 500fps w/ 0.28's at point blank, in the face. Did it suck? YES. Did I bitch? No, called hit and went back in. Super fun game.
(Ruined my condor jacket. Blood everywhere.
We were also getting dead checked at point blank during a scenario by these same guns. It's really not as bad as everyone makes it out to be. These guys weren't airsofters either, but they were MIL, so I guess it comes down to the shooter.
EDIT: This is in reply to the earlier posts about 540fps max limit. Not 700-1000, that's cavity piercing speeds...
Ár skal rísa, sá er annars vill
fé eða fjör hafa. Sjaldan liggjandi úlfur
lær um getur né sofandi maður sigur.
