The Expander MZ represents Barnes' commitment to muzzleloader hunters who demand performance and reliability. Built from 100% copper with a precisely engineered hollow cavity, these bullets are purpose-built for the unique demands of modern muzzleloading.

Key Features

• 100% Copper Construction: Ensures consistent performance and maximum durability
• Hollow-Point Design: Creates rapid, controlled expansion for quick, ethical kills
• Sabot System: Optimized for consistent velocities and improved accuracy
• Weight Retention: Typically retains 100% of original weight for deep penetration
• Controlled Expansion: Expands to twice original diameter, creating six razor-sharp copper petals

Performance Characteristics

These bullets are engineered to perform across the full velocity spectrum of muzzleloading—from modest traditional loads to modern high-velocity systems. The sectional density of 0.211 and ballistic coefficient of 0.207 provide the penetration needed for large game while maintaining the expansion characteristics hunters demand.

The six copper petals slice cleanly through tissue without fragmentation, ensuring maximum energy transfer and ethical, one-shot kills. Whether you're hunting with a traditional or inline muzzleloader, the Expander MZ delivers the confidence that comes from proven, repeatable performance.
