Conventional ammunition causes metal-on-metal contact between the bullet and bore, which can shorten barrel life and rob accuracy. Federal Premium's all-new American Eagle polymer-encapsulated Syntech bullet is designed to prevent this, while eliminating copper and lead fouling. Combined with specialized clean-burning powders, it helps your gun stay cleaner, longer, so you can shoot more—and shoot better. The exclusive Catalyst primer provides reliable, consistent ignition.
