I was wondering what you all thought would be the ideal wieght for a 5.56/.223 out of a short M4 like the police use or maybe an AR pistol. With the standard length rifles, I believe the heavier bullets (77grn) to be the best rounds. But would a barrel length of only about 10 inches hinder this relatively slow .223. I would think that a lighter, higher velocity round would be better in the short barrels. What do you all think
