The Federal Premium® Lead Muzzleloader Bullet's exclusive B.O.R. Lock MZ® System redefines in-line muzzleloader performance. It provides outstanding accuracy in a non-sabot design that's easy to load, scrubs fouling from the breech and ensures consistent bullet seating. The hard-hitting lead bullet penetrates deep.

Features:

• B.O.R. Lock MZ® System: Expanding polymer base cup engages rifling and seals the bore for extraordinary velocity and accuracy
• Required loading force averages about half that of most sabots
• Fouling-cutting ring scours powder residue from the breech as the bullet is loaded, resulting in consistent seating and reducing the need to clean between shots
• Tough, hard-hitting lead bullet with a polymer tip
