Assuming you're not making +P+ reloads or using Lehigh bullets, that's easily countered by a defense attorney providing ballistic evidence that your ammo is no more powerful or lethal than factory loads.
Easily countered? It is, and it isn't.
I cannot provide a cite or link (I'm not good at keeping those kinds of things), but I do recall hearing of a case (I think from Mas Ayoob's files) where handloaded ammo did play a big part. The specific details are out there (somewhere) basically, defense said wife shot herself. Prosecution said no, husband shot her from X feet away.
Their argument was based on the amount of powder burns. To further complicate matters the ammo came from a partial box of mixed reloads.
Now this situation is not the same as a self defense shooting, but some of the same principles apply.
Where there is doubt, your word on what, where, when, everything and anything can only be accepted if there is independent corroboration of some kind, and multiple reinforcements are best.
Your word and your records about what your handloads are, are all suspect. And it is also possible that testing of your ammo to determine it is what you say it is may not be allowed. That might be considered destroying evidence.
SO what does a crime lab do to have a standard against which to judge? With factory ammo, they can contact the factory, say we have ammo XXX (maybe even a lot# off a box) and the factory can give them all the specs they need. What powder, how much, etc. Generally courts will accept factory data pretty readily.
So the lab can get a pretty good idea what the powder burns ought to be a say one foot, vs 8 foot, for instance. Prosecutor is going to look at how your version of where the gun was when fired compared to what the lab says, if there is a significant difference, then you are going to have an uphill battle proving your innocence.
A self defense claim is a different matter yet, in court, because basically, you are admitting you did it (so burden of proof & reasonable doubt are different from a claim of innocent), and you are justified due to X, Y, & Z.
Making that claim in court gets you into what the law says specifically vs your actions. The idea of what a "reasonable and prudent" individual would do as a standard to judge your actions might enter into it.
Your defense has to be (at least in part) that you are that kind of individual, and so you did what they would do.
And the prosecutor is going to use anything he can find to show a jury that you are not that kind of person, so what you did was a violation of the law. Everything in your life at this point could be grist for that particular mill.
Zombiekiller on your gun, or ammo, while merely macabre humor to many of us could be seen in a very different light by someone in a jury box. How about other "responsible gun owners" calling it "childish and irresponsible", in print? Its difficult to convince some people how you could be so childish and irresponsible" in that aspect, and have been reasonable and prudent when you had to "defend" yourself. I think you get an idea where this could go?
yes, its your right to add any artistic embellishment you wish to your property. Even childish ones. But consider this, we spend a lot of time, energy, and money on our guns and ammo, seeking every tiny possible advantage in performance, should the worst happen.
If you are ever in a situation where a prosecutor is going to be shooting legal "bullets" at you, why would you let him use JHP when your choice of what to put on, or in your gun could restrict him to FMJ or better yet, blanks?
And, you know the worst part about the whole Zombie guns and ammo thing? They would be virtually useless against real zombies!
Real Zombies
are created by Voodoo magic. They can only be "killed" by a) destroying the Voodoo priest that raised them from the dead, b) salt (here, a shotgun with rocksalt would be effective), or c) somehow getting them to remember their name,(don't ask me how you would do that), in which case, they also remember that they are dead, and return to their graves, and cannot be raised again.
Zombie guns and ammo would only work against movie zombies (where brain shots kill them), and everybody knows those aren't real.
