The Remington Golden Saber High Performance Jacket is designed for law enforcement and personal defense and successfully combines match-type accuracy, deep penetration, maximum expansion and near 100% weight retention. This handgun ammunition is built around the hollow-point bullet design and the spiral nose-cut feature permits mushrooming at lower velocity without sacrificing penetration or terminal performance. The High Performance Jacket is made entirely of cartridge brass, which releases energy over longer distances while mushrooming. The cases are nickel plated for reliable feed, function and extraction. Primer and mouth waterproofing are standard.
