Barnes Expander MZ Muzzleloader 50 Caliber 250 Grain Hollow Point Ammunition

Barnes’ Expander MZ Muzzleloader ammunition in 50 caliber features 250 grain hollow point bullets constructed of 100 percent copper with a large hollow cavity designed for rapid expansion. The Expander MZ line produces more consistent shot-to-shot velocities and delivers better accuracy. These bullets are built to retain 100 percent of their original weight and expand to twice their original diameter, creating six razor-sharp copper petals that cut through game. Expander MZ ammunition performs reliably at both high and low velocities for one-shot effectiveness.
