Barnes' Spit-Fire T-EZ muzzleloader bullets load easier, even in tight bores. A sabot reduces the ramrod pressure required to load and seat these .50-caliber, flat-base bullets. T-EZ bullets deliver the same match-grade accuracy all Barnes' MZ bullets are famous for. The 100% copper bullets feature a polymer tip that enhances expansion and boosts BC for superior long-range ballistics. They expand at both close and extended range, creating six razor-edge cutting petals that maximize shock and penetration. Mfg: Barnes Bullets
