I have tested a number of military weapons that have full-auto capability, including M2 Carbines, M16' s, M14' s, AK' s and a number of different SMG' s. As far as rifle-caliber weapons go, I could usually hit the target with the first ttwo rounds, one at the point of aim, the next about shoulder level, and any subsequent ones went off into the air at ever-incresing angles. This is why I favor semi-auto fire, and aimed shots!!
