I've embedded this video at a specific time frame, if that doesn't work fast forward to 1:15 and then watch.
Finally! In this video, Chris Lasoya (a spokesperson for G.I. Milsim) admits that .50 cal paint does not travel as far as .68 cal paint. This is completely against what G.I. Milsim has been trying to tell us thus far (seen below in one example), despite physics and testing telling us that .68 travels further. It's nice to see the company has finally given up on trying to convince us that physics is wrong.
