and iron sighted, rack grade auto rifles, without ear protecton, better than the 50-50 LUCK ratio of a heads or tails coin toss. So much for the 308 having more "reach" than the AR-223. Hell, with the right loads in it, the 223 still has 75 grs at 2200 fps at that range, starting at 2800 fps in a 24" barrel. 24" AR, with 1" flashhider is SAME OAL rifle as 22" M1A and 3" flashhider. Still expands that V max sp real well at that range, has 800 ft lbs left at 300m, and makes 230 gr .45 jhp's (at 10 ft) look like the pussy loads that they ARE.
