The Premier Scirocco Bonded line is some of the most versatile and reliable big-game ammunition offered today. The expansion-generating polymer tip and boat tail base combine to defy air resistance at the front end and reduce drag at the back. 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. Finally, the bullet’s precise concentricity and secant ogive nose profile produce accuracy you would be proud of in match competition.
