"The Raptor Performance Ballistic Alloy the first non-lead Alloy Airgun Ammunition that increases velocity up to 25% over lead while maintaining match grade accuracy. Specifically designed as a hunting load the PBA enables airguns which normally shoot 1000 fps to shoot up to 1200 fps with tremendous penetration. In fact the ammunition is 50% harder than lead causing penetration to be enhanced by up to 100% in tests in actual hunting situations as well as ballistic mediums. Raptor PBA test results show ballistic stability at super-sonic speeds and up to 90% weight retention using the semi-pointed design. Comes in a 100 count .177 cal. rocket package.
