Barnes Expander MZ 50 Caliber 250 Grain Hollow Point Muzzleloader Ammunition

The Barnes Expander MZ is a 50 caliber, 250 grain hollow point bullet engineered for muzzleloaders. Constructed from 100 percent copper, it features a large hollow cavity designed for rapid expansion. The Expander MZ produces consistent shot-to-shot velocities and delivers improved accuracy. These bullets are built to expand to twice their original diameter, forming six razor-sharp copper petals that cut through game. The Expander MZ typically retains 100 percent of its original weight and performs reliably at both high and low velocities, delivering deadly performance for one-shot kills.
