20 rds. Premier® SwiftTM SciroccoTM Bonded Ammo. A big game ammo breakthrough!

A half-century of developments combine to create the remarkable Swift™ Scirocco™ Bonded Bullet. The expansion-generating polymer tip and boat tail base join forces to defy air resistance at the front end, while reducing drag at the back. Meanwhile, the progressively thickening, heavy-based, pure copper jacket is bonded to the lead core to preserve bullet integrity and retain over 75% of its weight at all velocities. And finally, the Bullet's precise concentricity and secant ogive nose profile produce accuracy you would be proud of in match competition.
