Designed for personal defense and medium-game hunting XTP Mag bullets provide the same controlled expansion accuracy and dependability that have made XTP bullets a favorite among target shooters and hunters alike. But XTP Mag? bullets are designed to take things a step further - withstanding the higher velocities and impacts of ultra-powerful magnum handguns while delivering even deeper penetration than standard XTP bullets.Precise serrations divide the XTP Mag? into symmetrical sections strategically weakening the jacket and initiating controlled expansion even at low velocitiesTotal uniformity of core density ensures balanced expansion as well as in-flight stabilityExpansion is controlled by varying jacket thickness down the length of the XTP Mag? providing a definite advantage over plated bullets which have a uniform jacket thickness over the entire bulletOn revolver bullets the cannelure helps achieve accurate consistent crimping. All cannelures are applied before the final forming process to eliminate any distortion to the finished bullet
