Assuming you are going to load said rounds in your concealed carry pistol or home defense firearm, do you really want to load something with a gimmicky or flippant name? Is that what you want the jury seeing? Prosecutor to jury - "Mr. Jones was so out of touch with reality that he actually purchased Zombie Max ammunition." Holding box up for effect. "The deceased was a homeless man with tattered clothes and open sores on his face. Did Mr. Jones think the deceased was a Zombie?"
No thanks, I'll stick with something like Critical Defense, Critical Duty, Personal Defense, etc.
