Federal Ammunition .50 caliber, 350-grain lead-tipped muzzleloader bullets are engineered for consistent seating and dependable performance in muzzleloading rifles. The design uses the B.O.R. Lock MZ system with an expanding polymer base cup that engages rifling and helps seal the bore. A fouling-cutting ring scours powder residue during loading to promote repeatable seating, and the polymer tip offers reliable profile and flight characteristics. Each box contains 15 rounds.
