Check the pic I posted back around 45. The number is micro etched repeatedly all over the base of the slug, dozens of times. That's how only 20% of the slug will give an entire number.

I see your point. I could go into a long dissertation of how their numbers are faulty...but this has nothing to do with preventing crime, a person intent on commiting crime can circumvent this technology as stated in many of the posts above...And as you and several others elude, this has everything to do to making it difficult if not prohibitive for innocent persons to exercise their 2nd Amendment rights...And also...making the company that holds the technology patents rich...from your post in #50 "A licensing fee will also be applied to each bullet sold."
