I hate to break it too ya mate but your gun (if chronoed properly) will "hurt" jus the same as the next gun. All paintball markers fire at the same velocity, but youll find that the impulse is a better marker than site guns.
The legal limit at most places is under 285fps.
P.S Dont flame the newbie!
P.P.S The Impulse is a wicked marker. U wont be dissapointed!
