Let me put it this way:
[1] I practiced law for over 30 years. I'm also an NRA certified instructor (Basic Handgun, Personal Protection In the Home, Personal Protection Outside the Home and Shotgun). I won't use handloads for self defense.
[2] It's not about the ammunition per se. It's about how certain factors, like handloaded ammunition, putting "Punisher" grips on your gun, walking around wearing a "Kill Them All and Let God Sort it Our" T-shirt at the mall, or other "gun nut" stuff can be used to attack your character and credibility. This is important because if you're in trial at all, somebody in authority thinks it wasn’t a “good shoot.” Your testimony might be crucial to establishing that your use of lethal force was justified. So the prosecutor in closing argument paints a vivid word picture for the jury of you in your workshop in the small hours fiendishly concocting super lethal “bullets.” If the jury can be convinced by the prosecutor that you're a junior Rambo wannabe, they just might not be inclined to believe your story, and SuzySoccermom, as she decides whether to believe you about how you had to shoot that nice gang member, is wondering why ordinary, store bought ammunition wasn’t lethal enough to satisfy your perverted blood lust.
[3] Of course, if one is unlucky enough to be on trial, the use of handloads could be only one, perhaps small, factor. But personally, I'd rather avoid any of these sorts of "wild cards" altogether. Even though I may have an explanation, I know from experience that the less I have to explain, the better off I am. I can easily limit what I have to explain without impairing my ability to defend myself. I think good quality, commercial JHP ammunition would be perfectly satisfactory. And if someone wants to question my use of JHPs, I can point out that’s what the local police use.
[4] This is just what I do and why, based on my training and experience in the legal profession. Each of you may, of course, make his or her own choice.
[5] And mljdeckard, welcome to the practice of law. It's an interesting and challenging profession. However, you may not want to be so quick to decide how you might handle things in the future. There's much to learn and an element of real artistry to successful trial advocacy, criminal or civil. When you find yourself in trial, you will use whatever you have in whatever manner you have decided is to your best advantage, as long as it's within the rules.
[6] And HANDLOADER, as I see it, there's no good, common sense answer without having "to dance through the maze of smoke", because it's all about the tactics lawyers use in trial; and there's sure a lot of smoke there. It may not be pretty and may go against our notions of how things ought to be and justice served. But it is a fact of life.
