SpeerA(R) Gold Dot was the original bonded-core ammoa |and it's still the No. 1 choice of law enforcement worldwide. Speer utilizes Uni-CorA(R) technology, which bonds the copper jacket to the lead core one molecule at a time. This virtually eliminates core-jacket separation through hard impact-so it retains energy and causes more devastation, even through barriers. That's why Gold Dot is the gold standard for personal protection. Order today!
