The Remington Premier Scirocco Bonded ammunition features polymer tip ballistics with weight retention as the expansion generates a polymer tip and boat tail base to defy air resistance at the front end and reducing back drag. The heavy based, pure copper jacket is bonded to the lead core to preserve the bullet integrity and retain 75% of weight at all velocities. This load is designed for medium to big game hunting and pushes a 180 grain bonded Scirocco bullet at 2700 fps.
