Speer LE's Gold Dot Duty Rifle: Speer LE Gold Dot Duty Rifle is now available for agencies. Gold Dot rifle bullets are optimized to ensure expansion out of barrels down to 10 inches at a wide variety of velocities out to 200 yards. Like their handgun counterparts, the Gold Dot rifle bullets are constructed using Gold Dot technology. The process of joining the jacket and core one molecule at a time eliminates the potential for the leading cause of bullet failure-jacket/core separation. It also ensures impressive weight retention through barriers as tough as auto glass.
