I know this isnt what my thread was about, but I'm glad you mentioned it. I keep seeing this over and over and over. What's the logic behind this statement? How would anyone even know its a handload once its already spent? I know people, including some cop friends, that couldnt walk into my loading room and tell me the difference in my stuff and the factory stuff laying around. How and the world would they figure it out once the bullet and powder are gone and the primer is burnt on the inside?
No one can tell my handloads from factory ammo either.
Here are the legal issues:
After use in a defensive situation, your gun & ammo will be confiscated. If you are charged (which is likely), part of the evidence presented will be test results on your gun & ammunition. With factory ammo, the test will be simple to reproduce. With handloads, it will be much more complicated - what brand of primer, what type of powder, what was the powder charge, what brand & weight of bullet, etc.
A more-serious issue: The D.A. will say something like, "Ladies & gentlemen of the jury: The defendant was not satisfied with the lethality of regular factory ammunition used by police officers; he wanted to participate in the making of his own, home-brewed ammo to increase the amount of injury to his poor, helpless victim." Of course, that is all B.S. but juries aren't all gun people & they may believe the B.S. especially if they are anti gun. Your future freedom will be at their mercy & you don't want to provide any help. Other things that can hurt you - grips with skulls on them, ammo that is called "R.I.P." The D.A. will use those to make you appear obsessed with death, shooting, etc. I also wouldn't have a lighter trigger in a defensive gun. "This defendant put a lighter trigger in his gun to enable him to shoot more bullets faster into his victim to ensure more bleeding & death."
What would your answer be if you're asked, "Why wouldn't you use regular factory ammunition that police use? You can do more research on this subject by asking experts in that field - like Massad Ayoob.
