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