As a CCW Instructor, who's been through the Legal briefing more times than I care to remember, DO NOT, under ANY circumstances, carry handloads or modified ammunition as your CCW self-defense rounds. No, it's not illegal. However, living in the sue happy world we inhabit, and the over abundance of blood sucking ambulance chasing attorneys out there, do you really want to stand in front of a jury and explain why your hand rolled, hotter than factory spec stuff was "necessary" to stop little Johnny the choirboy? Yes, I said NECESSARY!!!! Logic goes out the freakin' window when this subject comes around
Roll what you want, shoot what you want, hunt with what you want. But DO NOT carry it for CCW. Otherwise, you WILL be portrayed as the evil, I hid my gun so I could kill a bad guy and save the day, John Wayne type. Oh, and look, I even made my own "mankiller" bullets just to be sure I did the job right
You think I'm making this stuff up???? It's not worth a $30 box of premium self defense loads to deal with this kind of crap. most of the people you'll end up trying to convince (i.e. your peers on the Jury) won't know diddly doodle squat about guns or ammunition. But, that slick young lawyer looking to make a name for himself will be absolutely sure they "know" you're a gun fanatic, an anti-social element who is out looking for trouble so you can shoot someone with your super duper manstopper killing machine. Understand, yes there is a lot of sarcasm in this post. Good people's lives have been ruined at best, destroyed at worst, over a box of ammo so they could save a buck. Just don't do it, but it is legal, for now.
