Speer began manufacturing bullets during World War II and today the company offers a range of options including Speer Deep Curl Handgun Bullets. These bullets are designed with a boat tail great for long-range shooting excellent expansion and a high ballistic coefficient. These bullets directly compete with the famous Sierra GameKing bullet which speaks volumes. With these Deep Curl Handgun Bullets a preformed lead core and plated jacket are fused at the molecular level. This unique technology produces a slightly cupped flat base design that enhances accuracy. Because of the jacket and core bonding there is no possibility of separation following impact.
