Muzzleloaders are called primitive weapons, but the Federal Premium® Muzzleloading line shatters that perception. Our all-new technologies give hunters more reliability, consistency and accuracy than ever before.
B.O.R. Lock MZ™ System
The exclusive B.O.R. Lock MZ System provides outstanding accuracy in a non-sabot bullet design that's easy to load, scrubs fouling from the breech and ensures consistent bullet seating. The system's foundation is a polymer cup that is permanently attached to the bullet base. Before ignition, the polymer cup remains positioned at the rear of the bullet, with the forward obturating ramp exposed. At this point, only the fiber-reinforced base of the cup is in contact with the barrel. At ignition, the polymer cup slides forward and over both obturating ramps, creating the bullet's bearing surface and engaging the rifling. The resulting gas seal is incredibly efficient, optimizing accuracy, velocity, consistency and shooter confidence.
The fiber-reinforced ring at the bottom of the B.O.R. Lock MZ cup scours powder residue from the breech as the bullet is loaded, resulting in consistent seating and reducing the need to clean between shots. Required loading force also averages about half that of most sabots.
This proven copper-alloy bullet design features a polymer tip, with a deep, hollow cavity and skiving that allows for consistent, devastating expansion. Its high ballistic coefficient flattens trajectories and minimizes wind drift.
