Barnes Bullets Expander MZ 54 Cal Muzzleloader Hollow Point 275 gr - 24 Pack

The Barnes Bullets Expander MZ 54 caliber muzzleloader hollow point rounds are purpose-built for inline rifle hunters who demand reliable, lethal performance downrange. This 24-pack of 275-grain projectiles combines Barnes' time-tested hollow point design with the velocity consistency and accuracy that modern muzzleloading demands—whether you're hunting at point-blank range or stretching your shot beyond 150 yards.

What sets the Expander MZ apart is its solid copper construction and broad hollow cavity engineered specifically for muzzleloader velocities. Unlike traditional lead-core designs, these all-copper projectiles expand reliably across a wide velocity window, delivering consistent performance whether your inline rifle shoots at lower or higher muzzle velocities. The expansion mechanism creates six razor-sharp petals that slice through vitals with surgical precision, while the projectile retains its weight throughout the wound channel for deep penetration where it matters most.

Each round is built to expand to roughly double its original diameter on impact, generating the kind of wound trauma that translates to quick, ethical kills. Because they're solid copper with no fragmentation, you get the weight retention that keeps energy downrange and ensures the projectile performs as designed, shot after shot. For hunters running inline muzzleloaders who won't compromise on bullet quality, the Expander MZ delivers the accuracy and one-shot confidence that separates clean harvests from long tracking jobs.

Frequently Asked Questions

Are these bullets designed for inline muzzleloaders?

Yes. The Expander MZ line is engineered specifically for inline rifles. Barnes tuned the hollow point cavity and expansion characteristics to work reliably across the velocity range of modern inline systems.

What kind of expansion should I expect at typical hunting distances?

These bullets are designed to expand to roughly twice their original diameter, creating six razor-sharp petals. They perform reliably across both high and low muzzle velocities, making them effective whether your inline rifle shoots slower or faster loads.

Will the bullet stay intact in the game, or will it fragment?

The solid copper construction means no fragmentation. These rounds typically retain 100% of their original weight throughout penetration, ensuring deep wound channels and consistent performance.

How many rounds are in a box?

This package contains 24 rounds of 54 caliber, 275-grain Expander MZ projectiles.
