The Barnes Bullets Expander MZ is a 50-caliber muzzleloader bullet engineered for hunters who demand clean, ethical harvests from their black powder rifles. This hollow-point design comes in 250-grain weight with an included sabot, delivering the ballistic consistency and terminal performance that modern muzzleloading demands. Whether you're hunting whitetail, elk, or other game, these bullets are built to produce reliable, one-shot kills across a wide velocity range.
What sets the Expander MZ apart is its proven expansion characteristics. Upon impact, the hollow point initiates controlled expansion to roughly twice the original diameter, creating sharp copper petals that slice through game without fragmenting. This aggressive but controlled expansion means energy transfer stays focused where it matters—delivering devastating effect on vital areas while minimizing waste and meat damage. The design performs consistently whether you're loading lighter or heavier powder charges, giving you flexibility in your load development without sacrificing reliability.
Each pack contains 15 bullets, so you're getting a solid quantity for a season of hunting or range work. The sabot inclusion simplifies your reloading workflow—no need to source components separately. If you're serious about muzzleloader accuracy and terminal performance, the Expander MZ deserves a spot on your bench.
