Winchester USA Varmint & Predator Rifle Ammunition

Backed by generations of legendary excellence, Winchester "USA White Box" stands for consistent performance and outstanding value, offering high-quality ammunition to suit a wide range of hunter's and shooter's needs. Ammunition may show discoloration which is caused by a process known as annealing. This is completely normal.Please Note: While the 5.56x45mm will fit in a .223 Remington chamber, the 5.56 is a military round that runs at higher pressures than its .223 counterpart and is not recommended to be fired in a .223 Remington Chamber.
