Hornady XTP bullets are famous for their ability to expand reliably across a wide range of velocities. Special features in the nose facilitate and control expansion on impact. Others, like the cannelure, ensure the jacket and core remain locked solid during expansion. XTP bullets consistently deliver the deep, terminal penetration needed for one-shot kills. The XTP is one of the most accurate pistol bullets ever made, and it's just as accurate in your muzzleloader. Good shooters with quality barrels can consistently achieve sub 1-inch groups at 100 yards. No additional lubricants or patches are necessary with Hornady's XTP bullet/sabot combinations. Because they load easier, you can reload for fast follow-up shots.
