Barnes Expander MZ 54-caliber muzzleloader bullets deliver 100% copper construction with hollow-point expansion for consistent velocities and reliable one-shot performance on game.
The Expander MZ represents a purpose-built solution for the serious muzzleloader hunter. These 275-grain projectiles are engineered specifically for the demands of black powder shooting, combining the proven principles of modern bullet design with the unique requirements of muzzleloading firearms.
100% Copper Construction: Each bullet is formed from pure copper, eliminating the lead core found in conventional ammunition. This design choice delivers several advantages:
The hollow-point cavity initiates rapid, controlled expansion at both high and low velocities. Upon impact, the bullet expands to approximately twice its original diameter, creating six razor-sharp copper petals that slice through vital areas with devastating effect.
Key Performance Features:
Muzzleloader hunting demands ammunition that performs reliably under variable conditions. The Expander MZ addresses the unique ballistics of black powder by maintaining consistent velocities and delivering predictable expansion. This translates to greater shooter confidence and more ethical, one-shot kills on game.
