Just field the damn 6.8SPC or .276 peterson or whatever the hell already and stop trying to eek out every last cunt-hair of terminal effectiveness from the .223. This has just gone too far, IMO. The military has proven that money doesn't matter, anyway. Look up the Paladin. The carbine competition. How much money was just spent on picking a PISTOL!? Surely we could re-barrel some M4's and drop in new bolts.
