Barnes Bullets Expander MZ 50 Cal 250gr 15/Box Muzzleloader Bullets

The Barnes Bullets Expander MZ muzzleloader projectile brings the legendary all-copper X-Bullet performance to black powder hunters. Built around a large hollow cavity and a solid copper body, this 50 caliber bullet is engineered for rapid, controlled expansion across a wide velocity window, producing a wide wound channel at black powder velocities for clean, ethical harvests.

At 250 grains and a .451" diameter, the Expander MZ is a serious hunting projectile for 50 caliber muzzleloader rifles. The hollow point cavity is paired with Barnes' signature multiple expansion petals, allowing the bullet to open to roughly twice its original diameter and form six razor-sharp copper cutting edges while retaining the bulk of its mass for deep penetration. The 100% copper, lead-free construction delivers consistent, reliable expansion at both high and low velocities, making it a versatile hunting bullet for deer, elk, and similar big game.

These Expander MZ muzzleloader projectiles are designed to be loaded with a sabot in .50 caliber muzzleloader barrels, pairing with your preferred black powder or pellet charge and ignition system. Each box contains 15 projectiles.
