10" barreled 223=60 grs, 2600 fps.
The load is 26.5-27.0 grs of AA2520 powder (depending upon the barrel). no, such loads are not dangerous in 5.56 chambers, either. That 60 gr softpoint bullet still has 2000 fps left at 200 yds, and doesn't go below the 1800 fps of minimal velocity for expanding a softpoint (reliably, in flesh) until it has passed 250 yds. 60 grs at 1800 fps is the same 425 ft lbs as a snubby 357 revolver has at 5 ft of range.
250 yds covers well over 95% of the non-accidental hits in rifle combat, so such a shorty 223 is quite a capable arm (contrary to the claims of the ignorant). It certainly beats the 7.62x39 AK, the .30 Carbine, the 45-70, the pistol caliber carbines, and all the SMG'S (to say nothing of the 12 ga with slugs) as to effective range (when scoped), yet it is just as small and lw as the smg's. Since so many claim that the 12 ga has all the range "needed", it's strange to see the same people claiming that the shorty 223 "lacks enough range". Such a 223 easily has 2x the effective range of the 12 ga, and in reality, it probably has 3x the 12 ga's realistic effective range.
