Another rifle caliber, the 30.30 caliber, was responsible for penetrating three officers' armor and killing them in 1993, 1996, and 2002. This ammunition is also capable of puncturing light-armored vehicles, ballistic or armored glass, armored limousines, even a 600-pound safe with 600 pounds of safe armor plating.
It is outrageous and unconscionable that such ammunition continues to be sold in the United States of America. Armor-piercing ammunition for rifles and assault weapons is virtually unregulated in the United States. A Federal license is not required to sell such ammunition unless firearms are sold as well. Anyone over the age of 18 may purchase this ammunition without a background check. There is no Federal minimum age of possession. Purchases may be made over the counter, by mail order, by fax, by Internet, and there is no Federal requirement that dealers retain sales records.
