Hollow point bullets don’t always work when compromised by an attacker’s clothing, especially denim and leather. NOT with HornadyA(R) Critical DefenseA(R) Ammo. Its patented polymer Flex TipA(R) design with FTXA(R) bullet always delivers big, controlled expansion. PLEASE NOTE: Hornady has temporarily suspended nickel plating due to supply shortages. These rounds will feature a traditional brass case instead.
