Barnes Expander MZ 50 Caliber 300gr Muzzleloader Ammunition

Barnes brings its X-Bullet technology to muzzleloader hunting with the Expander MZ in 50 caliber, 300 grain hollow point construction. Built entirely from copper, these bullets feature a large hollow cavity engineered for rapid and reliable expansion. The Expander MZ design produces more consistent velocities shot-to-shot and delivers improved accuracy, supporting more one-shot kills. Expander MZ bullets perform effectively across the full velocity spectrum, from high to low impact speeds. These bullets typically retain 100 percent of their original weight while expanding to twice their original diameter, generating six razor-sharp copper petals that cut through game.
