When WE M4's first came out in the US. We went and bought some. Knowing they came with a 500+fps nozzle and a 400fps nozzle, we changed them out... Turns out they were both 500+ nozzles...
I shot KrookedAtmosphere in the ass from about 15 feet away with 0.28s. It left a sold dent in his jeans and a yelp.
During a training contract with the CF, I got shot in the jaw from <5 feet with a WE M4 shooting 500+ with 0.28g BB. Instant blood letter, ruined my condor jacket, totally worth it.
These are the only two instances I know I've shot or been shot by a hot gun.
Ár skal rísa, sá er annars vill
fé eða fjör hafa. Sjaldan liggjandi úlfur
lær um getur né sofandi maður sigur.
