Barnes Expander MZ .50 Cal 250gr Muzzleloader Bullets

Barnes Expander MZ Muzzleloader Bullets

The Expander MZ represents Barnes' proven X-Bullet technology, specifically engineered for modern muzzleloaders. These all-copper, hollow-point projectiles deliver the kind of performance that separates one-shot kills from wounded game.

Design and Construction

100% Copper Construction: Each bullet is manufactured from pure copper with a large, hollow cavity designed for controlled, predictable expansion.

Sectional Density and Ballistics: With a sectional density of 0.211 and ballistic coefficient of 0.207, these bullets maintain velocity and energy downrange better than conventional muzzleloader projectiles.

Performance Characteristics

• Consistent Velocities: Shot-to-shot velocity variation is minimized, translating directly to improved accuracy and shooter confidence
• Reliable Expansion: Expands to twice the original diameter, creating six razor-sharp copper petals that slice cleanly through tissue
• Weight Retention: Typically retains 100% of original weight—no fragmentation, no energy loss to bullet breakup
• Velocity Range: Delivers deadly performance at both high and low velocities, making these bullets forgiving across different powder charges

Why Choose Expander MZ

Seasoned muzzleloader hunters trust these bullets for their ability to deliver one-shot kills on large game. The combination of consistent ballistics, controlled expansion, and deep penetration makes the Expander MZ the choice when confidence matters most.
