Winchester Super-X Silvertip offers a unique combination of power, precision, reliable functioning and on-target performance via a specially engineered jacketed bullet. Originally developed for Law Enforcement as a replacement to traditional hollow points, this bullet delivers penetration and rapid energy release with virtually no weight loss or bullet fragmentation. Super-X jacketed hollow points have notched jackets to ensure positive expansion. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
