Nosler Defense ammunition is loaded with Nosler Bonded Performance handgun bullets for maximum accuracy, consistency and dependability. Nosler's Bonded Performance bullets were developed with the same technology as Nosler's renowned AccuBondA(R) line which eliminates the possibility of jacket/core separation resulting in higher weight retention and maximum barrier penetration. Designed with a tapered jacket and specially engineered lead-alloy core, Bonded Performance bullets exhibit predictable expansion and straight-line penetration in a variety of media. Loaded to the strictest tolerances with high-performance powder charges and Nosler Premium Brass, every round of Nosler Defense ammunition is visually inspected to ensure reliability.
