Nosler Defense ammunition is an excellent self-defense load featuring the new Bonded PERFORMANCE bullets. PERFORMANCE bullets were designed with the same technology as Nosler’s trusted AccuBond bullet which eliminates the possibility of jacket/core separation. The resulting bullet retains nearly 100% of its original weight. At the same time, a tapered jacket and lead alloy core produce reliable expansion. Nosler Defense ammunition is available with either a polymer tipped or jacketed hollow point bullet.
