These are from Cartridges of the World by Frank C. Barnes and various Internet sources.

You know, I was gonna follow this up with a list of guns chambered in these calibers, but there were just too damn many.

I am still miffed that of all the .223 weapons, they showed an AR and a Daewoo first.  Grr.

Why not be miffed for the [b]BEST[/b] reason? Although the projectile is obviously [b].224[/b] in diameter, the press has been calling it [b].223[/b] since day one. (Long before the casing was found at the school shooting. And that casing could very well be a [b]"DROP"[/b] picked up at a range somewhere.) The press, and perhaps some elements of the LEOs supplying them with their "information" have an agenda. [b]NEVER LOSE SIGHT OF THAT OBVIOUS AGENDA!!!!![/b]

Someone (I think it was Patrol Mom) noted on GlockTalk that the ratio of dead to shot is 9/11. Coincidence? Or were the two woundings intentionally shot low, so they would survive?
