A streamlined semi-spitzer ogive, boattail base and tack-driving accuracy make the Barnes Spit-Fire™ MZ a great choice for difficult long shots. Deadly at high and low velocities. Six razor-sharp copper petals create massive shock, deep penetration, and double-diameter expansion. Retains virtually 100 percent of its original weight. Available in .50 caliber, 245- and 285-grain bullets in 15- and 24-bullet packs.
