Barnes Expander MZ 50 Caliber 300 Grain Muzzleloader Ammunition

Barnes’ Expander MZ is a muzzleloader bullet engineered from 100 percent copper and features a large hollow cavity designed for rapid expansion. The 50 caliber, 300 grain Expander MZ produces more consistent shot-to-shot velocities and delivers improved accuracy for greater confidence in the field. These bullets perform reliably across both high and low velocity ranges. Built tough for deep penetration, Expander MZ bullets typically retain 100 percent of their original weight and expand to twice their original diameter, creating six razor-sharp copper petals that slice through game.
