The Swift Scirocco II is a polymer-tipped, bonded hunting bullet renowned for its high ballistic coefficient and devastating terminal performance. The proprietary Scirocco bonding process molecularly fuses the tapered jacket to the lead core, ensuring 70%+ weight retention through heavy bone and muscle. Its secant ogive and 15-degree boat-tail deliver exceptional aerodynamics and accuracy at extended ranges. The progressive thickness jacket provides controlled expansion across a wide velocity range. The Scirocco II is particularly effective on large, tough game like elk and moose, combining the accuracy of a target bullet with the terminal performance of a premium hunting bullet.
