Federal Premium .50 calibre 350 grain lead muzzleloader bullet using the B.O.R. Lock MZ system. It is a non-sabot design that is easy to load and seats consistently.

• Polymer base cup expands on ignition to engage the rifling and seal the bore for velocity and accuracy
• Required loading force averages about half that of most sabot bullets
• Fibre-reinforced polymer ring scrapes powder fouling from the breech as the bullet is seated, for consistent seating depth and less cleaning between shots
• Tough, hard-hitting lead bullet with a polymer tip
