Gold Dot is the No. 1 load for law enforcement, and we offer the same performance to you. Each load features Speer's exclusive Uni-Cor method, which bonds the jacket to the core one molecule at a time at the very beginning of the bullet construction process. This virtually eliminates core-jacket separation and creates a precision hollow point that is accurate, tough, and unbelievably consistent.
