Federal® B.O.R. Lock™ Muzzleloader Bullets - 350 Grain Lead

Federal™ Muzzleloader Bullets are the most innovative muzzleloading projectile in decades that are redefining the accuracy and performance of modern, in-line muzzleloaders. The exclusive B.O.R. Lock MZ™ System provides outstanding accuracy in a non-sabot bullet design with sealing mechanism integral with the bullets, that is easy to load and approved for hunting in most areas. Fouling-cutting ring scours powder residue from the breech as the bullet is loaded, resulting in consistent bullet seating and reducing the need to clean between shots.

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 obtruding ramp exposed, and only the fiber-reinforced base of the cup in contact with the barrel. At ignition, the polymer cup slides forward over both obtruding ramps, creating the bullet's bearing surface, keeping the bullet seated and engaging the rifling. The resulting gas seal is incredibly efficient, and optimizes accuracy, velocity and consistency for shooter confidence.

The Federal™ Muzzleloader Bullets all-new technologies give hunters more reliability, consistency and accuracy than ever before. The heat-treated, lead design features a polymer tip, with a deep, hollow cavity and skiving for consistent, devastating expansion. With no bulky sabot, required loading force averages about half that of most sabot bullets. In addition to extending the effective range of hunters and shooters, the Federal™ Muzzleloader Bullets feature a high ballistic coefficient for flatter trajectories and less wind drift to increase maximum effective range in the field, while delivering plenty of knockdown power with consistent expansion and weight reduction.
