The 2nd amendment was written for a reason. You got a problem with it? Fine, that's why there are 2 clear ways to amend the constitution. Go ahead and get that level of support for your cause and do something about it. The burden is on the liberals to garner support/justification. Not those that understand the logic behind the 2nd amendment.

I think they will be roughly equivalent in close quarter defense situation.

Even between the .357 and 9mm there is a difference in stopping power of close to 10ish%. Full metal jacket and simi-wadcutters can get significantly lower 1 shot stops than hollow points.

Kind of a fun table to checkout:

I've seen it many times. It's interesting, but doesn't matter. A guy who received 1 blast of 12ga loaded with 00 buckshot from typical legal self-defense distance will be as dead as one who got full mag from 9mm P226. So for this particular practical purpose 1 shell = 1 mag.

Well......He would also be just as dead from 1 .357 JHP. So...

Also, the difference is that you are not going to shoot and kill 6 different people with 1 shot gun shell.

Well, the real question is not 30 rounds but 11+ because that is the limit of the ban.

No, you said there were occasions where a high-capacity magazine would be useful for self defense. It became the question when you brought it up.

This guy:

Required seven shots to fend of two assailants who had guns on him. I dunno, maybe if there were three he would have needed more than 10 rounds...

I asked for an actual account, not a "maybe".

And here is a guy that fired 5 times to save a cop being attacked:
http://xavierthoughts.blogspot.com/2006/02/armed-citizen-saves-cop-in_114058863533452150.html

So why would he need a 30-round magazine, and how is that self-defense?

I have also heard of people getting in shootouts when their shop is robbed and while they fend off their attackers they fire 11+ rounds, but it is with multiple revolvers, etc. Sorry, no links though.

Sorry, links are required.

Oh, here is one where a guy goes through several high capacity magazines:

Interesting thing from this story is that he fired 105 shots, most of which were meant not to kill, but to put his assailants under cover until the police arrived. If he had been working with less ammo he probably would have had to shoot to kill.

O.K., but I asked if anyone has "successfully defended himself against an illegal attack, in a situation not of his own making, where a 30-round magazine was necessary." This man was not attacked. His store was being robbed, but he was not in the store. Rather than letting the police do their job, he WENT to the store to fight the robbers. Clearly a situation of his own making.

A while ago there was a talk on the radio about this pregnant woman who shot the rapist who broke into her house and tried to rape her.

Of course it was on NPR so they were having a usual snobbish philosophical debate if she should go to jail or not. Either way she was found right in her actions.

Surely she didn't need a 30-round clip for that?

AIS, you are awesome.
