as to the whole 9mm/45 thing it seems to me that most people think its a choice between carrying 15 rounds of 9mm(baretta) and carrying 7 rounds of .45(1911). personaly I split the difference and got a glock that carries 10 rounds of .45acp.

The.223 caliber rd is the same as the 5.56 mm rd, the difference being wether you measure it by the inch standard or the metric.

Why not 13? The G21 I know packs a baker's dozen.

Typically they are as mentioned above, difference in standard and metric measures, however if you are a reloader or shooting with a chrono you will notice a difference. The wall on mil-spec stuff is typically thicker and the round hotter. I mean hotter in a couple ways, pressure spike and actual fps. Commercial mfg is typical at the lower end of the spectrum in most specs, however there are a few who will up the ante to the mid and upper end of the "charts". Reasoning behind commercial mfg loading at the lower end is purely due to legalities and the sue happy folks. 5.56 is always considered a full-metal jacket due to the Geneva Convention, I have seen some that wasn't, but it was only at the base where the lead was poured in. I'm not sure the reasoning behind not allowing FMJ...IMO they leave more wounded versus dead. Not a good thing when in a conflict/war.

I've also heard that you have to be carefull about useing the wrong one in the wrong gun because the difference in chamber pressure could possibly cause a chamber to fail. my ar being marked for .223 is why I have only used .223. if it was marked 5.56 I would probably look for actual 5.56 ammo for it.

It takes more personnel and resources to take care of wounded than dead.

I don't have one yet, but I will soon. I know my Avitar says I'm in DC, but I in fact live across the Patomac in the great state of Virginia for the very reason of honoring my 2nd Admin. rights. Don't quite know what I want, but I do like firing a 308. I was at the NRA range the other day and in the booth next to me was an ar accepting .45 with suppressor and laser sights. It looked so cool. Can't wait to get my AR. I just might make my Bday come a little earlier this year. Nice pics Gentlemen.

size...the g30 is a subcompact...I had planed to use it after I got my ccw but I never got around to getting ccw and don't know if I ever will to tell you the truth

Nice! That has to be fun gun to shoot.

How does the G30 handle?

I have always been afraid it would get away from my meat hooks.

The 5.56 primers are specifically designed to be less "sensitive" to avoid preignition in a semi-auto or full-auto weapon system. .223 was more of a bolt action round prior to the AR platform and the primers on a standard .223 round were known for being "soft" in comparison to the 5.56 and therefore generally not recommended for use in the AR platform. Modern manufacturing and better tolerances have made this less of an issue. Just my 2 cents.

5.56 is actually a little bigger. You can notice when you groups go to heck with just switching from 5.56 round to .223 in a 5.56 barrel. The bullet will actually wobble on a very small scale. I've only seen this with my uncle's 5.56 but they say it common on some of the gun forums.
