Pro chrono? Thats a professional chronographer right? We have one of those on our team. Let me explain, its a guy who stands exactly 10 feet away from the marker, and the markler is fired into his stomach, and we judge the velocity of the marker by the loudness of his scream. Its a foolproof system, We find that it is hard to judge after a few markers have been chronoed though, usually after 5 or so markers all the screams are the same volume, must mean that the guns are all chronoing at the same velocity. Weird May have to take a look at that.Originally posted by 2scoops
