The Scirocco cut away shows how the unique combined design features make our new Premier Scirocco line some of the most versatile and reliable big game ammunition offered today. The expansion generating polymer tip and the 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 bullets precise concentricity and secant ogive nose profile produce accuracy you would be proud of in match competition.
