Casey,
I used to feel the same way until I took Judicious Use of Deadly Force with Mr. Ayoob. He articulately and forcefully explained why this is a hideously bad idea. He walked us through the arguments that the DA/Prosecutor will (and has) use against you.
"So, ladies and gentlemen of the jury--this man spent HOURS in his basement concocting the perfect ammunition for killing human beings! I know, it seems strange, but he locked himself away from the world and loaded these 'dum dum' bullets into meticulously prepared ammunition--a quasi religious experience for him--we can only guess what shortcomings drove him to this point...Most bullets explode when they hit something, but when these bullets hit you, YOU explode!! Look at these photos of the victim of this man's wrath and loathing of humanity....<pics>...So, Mr. Casey, and let me remind you that you are under oath--was it a plan to execute this man using your special death recipe, cop killer dum dum ammunition, or was he just unlucky enough to wander into your view while you were having a bad day?"
In short, it's a fight that you don't need in court. One less thing to explain/defend could mean your freedom, and all the money you (we) thought we were saving will end up in your lawyer's bank account.
Carry factory. That's my advice.
