Winchester Ammo USA556JF USA 5.56x45mm NATO 50 gr Jacketed Frangible 20 Bx/50 Cs

The USA556JF is ideal for high-volume short to medium range indoor and outdoor training and target use in modern sport rifles. It features a 5.56mm shell case and utilizes a lead-free brass-jacketed bullet with a frangible core and lead-free primer. The frangible core facilitates rapid bullet break-up once a hard target is hit thereby minimizing airborne lead at the shooter station as well as downrange lead in bullet traps.
