This muzzleloader version of the X-Bullet is 100 percent copper with a large, hollow cavity for quick, sure expansion. Barnes’ Expander MZ Muzzleloader Bullets produce more consistent shot-to-shot velocities and better accuracy than competing bullets deliver. The result? Greater shooter confidence and more one-shot kills. Expander MZ bullets deliver deadly performance at both high and low velocities. Expand to twice their original diameter, creating six razor-sharp copper petals that slice through game. No fragmentation–these tough, deep-driving bullets typically retain 100 percent of their original weight.br /br /Features:br /br /- 100% Copperbr /- Exceptional Accuracybr /- Full weight Retentionbr /- Razor Sharp Cutting Edgesbr /- Double-Diameter Expansionbr /- Deep Penetrationbr /- Effective at High and Low Velocitiesbr /- No Fragmentationbr /- Recommended for In-Line Rifflesbr /br /Specifications:br /br /- Caliber: .54br /- Diameter: .500br /- Weight: 275 Grainsbr /- Length: 0.871"br /- Sectional Density: 0.157br /- Ballistic Coefficient at 100 Yards: 0.184br /- Quantity: Per 15
