I think we are talking about two differant cases here. Criminal and Civil.
If its a ligit shooting we can narrow it down to one case. Before that happens, we have a coronors inquest to determine if a crime was commeted by the shooter or not. This will depend a lot on your state laws regarding self defence.
Assuming the shooting is ruled ligit, ( I wont deul on the criminal cases, let the tv cop shows handle that). So I'll limit my comments on the civil aspect.
When a bandit gets shot, he of course a bad guy, home invasion, car jacking, trying to steal your grandaughter, what ever, he get shot because he's a bad guy. Coronor inquest clears you, and the DA has no case so he's out of the picture.
So here comes the civil case, the bandit is no longer a bandit, he's the scout leader, chior boy, and all around super nice guy. This is where the lawyer comes in. The Chior boys lawyer is gonnna do everything posible to make you look bad. He's gonna deal more then just re-loads, but everything to cloud the issue (which also takes time which means more money to him and your lawyer). Besides the ammo you use, you're gonna have to convince him you didnt go wacko because of your military training (regardless of what it was), you're traffic record when you were a kid. What evil zombie killing groups you belong to , like the NRA, Turkey and Elk foundations, etc etc. The internet is great, run some of the topics you were part of through google and see if your name or nic comes up.
Any thing to cloud the issue. We's all seen it before, not just in shooting cases but traffic accidents and everything else. Thats why most departments, when an officer is involved in a shooting settle these cases out of court, not because the officer is wrong, but its often cheaper to settle up then fight the case. Lawyers are after billing hours, if the Bandit (now chior boys) lawyer can drag it out, he bills more hours, as does your lawyer who has to fight it. Lots of incient people are destroyed because of these BS lawsuits.
So take you pick, its not just ammo or gun you use, its about everything in your life. You can roll over hide in a bubble for fight it. No one can make that choice for you.
There is another option. The State of Wyoming is a bit independant, run buy a bunch of old ranchers and oil men who refuse to give up their guns and cave to the bs. Our Castle doc. has a clause, if the shooting is ligit, then YOU ARE EXEMPT FROM CIVIL LAW SUITS. Of Course you can sue anyone for anything, and its possible to sue you anyway to see if you come under Wyomings NO Civil Suit Rule. Our legislator saw that senario also, So if you are sued anyway, after it being ruled a ligit shooting. The State Flips the bill for the suit.
My sugestion is, to google Wyoming gun laws, take a copy of our Castle doc. to your State legislators and demand a simular provision in added to your laws.
Folks I've seen this, as I said, not just with guns, in my LE career I've been classified as Firearms expert (CSI Instructor) , Traffic Accident Reconstructionest, and Explosive expert, (EOD). Its not just firearms and shooting you have to deal with, its just about everything in your life.
The place to fight this is before you are involed in a shooting, through your legislator. We talk of Sheep Wolves and Sheepdogs, but dont let those terms be restricted to firearms. Be a sheepdog in everything you do.
