More correctly it was listed under
"Title 18, UNITED STATES CODE, CHAPTER 44 as amended by Public Law 103-322 The Violent Crime and Law Enforcement Act of 1994 (enacted September 13, 1994) 18 U.S.C. CHAPTER 44 § 921(a)(17)(B) the term 'armor piercing ammunition' means --" as armor piercing.
then ammended
"NOTE: THE FOLLOWING CARTRIDGES HAVE BEEN REMOVED FROM THE DEFINITION OF ARMOR PIERCING AMMUNITION:
5.56MM (.223) SS109 and M855 Ammunition, Identified by a green coating on the projectile tip.
U.S. .30-06 M2 AP, Identified by a black coating on the projectile tip."
SS109 and M855 should have never been listed in the first place. I think the M2 was reclassified because it was not designed with the intent to be used in a handgun.
Anyway, smoke up Johnny and shoot bunches of the stuff.
