deur Hornady · Sien besonderhede op vervaardiger se webwerf
Die Hornady SST (Super Shock Tip) koeël het 'n elegante, polimeer-tipped ontwerp met 'n InterLock-ring wat die kern en die jas meganies saamlock. Hierdie loodvrye koeël lewer verwoestende terminale prestasie met vinnige, kontroleerbare ekspansie. Die sekante ogive en boot-tail ontwerp bied 'n hoë ballistiese koëffisiënt vir vlak trajekte en uitstekende akkuraatheid op jag afstande. Die SST is veral effektief op mediumwild soos damhert en tropse, waar sy ontploffende ekspansie groot wondkanale skep vir vinnige, etiese dood. Sy kenmerkende rooi polimeertip begin ekspansie selfs by verminderde snelhede.
