Specifically designed for modern sporting rifles, Winchester Defender centerfire rifle ammunition includes Split Core Technology. This technology provides the ideal balance between expansion, retained weight and penetration in personal defense situations. The protected hollow point promotes sure feeding and initiates quick expansion and the expanded bullet provides high initial impact trauma plus critical penetration. Split Core Technology includes a front core that provides quick impact shock and a rear core that is welded to the jacket to assure maximum retained weight.
