They use a 90 gr VLD match bullet, at nearly 2800 fps, 1 in 6.5" rifling twist, and still have 1200+ fps left at 1000 yds. That's the same 250 or so ft lbs as a .38 has at 10 ft. So much for all 223's being limited to 500 yds, eh? 
In fact, the 223 AR has OWNED the 600 yd line at the High Power matches, since about 1997, when Berger first brought out his 80 gr VLD in .224". A 24" 223 will still have 1800 fps and 500+ ft lbs left at 500 yds, still expanding a softpoint and hitting out there like a 4" 357 hits at 10 ft. For realistic sniping, the 223 AR will serve just fine. Do you know what an HONEST sniper said? Carlos Hathcock said:" I made some good shots, but I missed a lot". This was in an interview with him, by American Survival Guide magazine, and he was a proven 1000 yd match champion. You are nothing of the kind, so much for your 308 and 1000 yd dreams, eh?
