DeepCurl Handgun Hunting bullets are tough for deep penetration that gives reliable performance every time. For those who seek challenges, try taking your next trophy with a handgun and make sure to load DeepCurl. Formerly known as Gold Dot Handgun Hunting, Speer uses the same bonding technology they always have in these outstanding handgun bullets. Speer Bullets electro-chemically bonds the jacket to the core to create a tough bullet for the harshest of conditions. Preformed petals give you controlled expansion and retained weight for deep penetration and excellent accuracy. Conventional reloading data developed for standard jacketed bullets should not be used to load DeepCurl rifle bullets. DeepCurl handgun bullets can use data from the Speer Reloading Manual #14.
