    Info on 5.56 NATO ballistics

    Anyone know where I can get reliable information on the ballistic characteristics of the 5.56 NATO round from different length AR-15 barrels? I'm under the impression that most 5.56 ammo will reliably fragment at speeds at or above 2,700fps, but I can't find good data on at what distances the bullets drop below that speed from different barrel lengths.

    For example, I've read online that from a 16" barrel, I can only count on 2700fps out to ~75 meters, but I spoke with a guy I trust today who said he believes it is closer to 300 meters. Obviously, one (or both!) of them are wrong. I need help!

    here's a good read, though not exactly what you're looking for in an answer:
