The man said self defense, he didn't say home defense.

Seriously, do a search. This question comes up repeatedly and some of us are getting tired beating the horse.

BTW, the issue isn't a TV myth. A cop in Virginia got convicted on an off duty shooting because the factory changed powders and the lab used a more recent production for their testing. He beat it on appeal with expert witness testimony from the factory, but he went through hell before doing so. There's no good reason to give the potential opposition a larger club to beat you with and raise the price of your defense at the same time. In the event of a similar event in factory ammo, the factory is a neutral third party providing exculpatory evidence. Whereas, you're a sniveling defendant trying to stay out of jail. Who has more credibility with the jury?

FWIW, there's at least one poster here who's comfortable carrying reloads. But, he's an attorney and is known to the justice establishment as a good guy. It didn't help the gent I mentioned earlier.
