The exclusive polymer coating in all-new American EagleA(R) Syntech(TM) prevents harsh metal-on-metal contact between the bullet and bore, eliminating copper and lead fouling. Combined with clean-burning powders and the Catalyst(TM) lead-free primer, Syntech loads keep your gun cleaner, longer, so you can shoot more-and shoot better. Freatures: Polymer-encapsulated Syntech bullet prevents metal-on-metal contact in the bore, eliminating copper and lead fouling, while extending barrel life Exclusive primer formulation provides reliable, consistent ignition Clean-burning propellants minimize residue and fouling Significantly reduces the required frequency of cleaning Absence of a copper jacket minimizes splash-back on steel targets Less perceived recoil
