Speer Gold Dot .40-Caliber .400-Diameter 165-Grain Hollow Point bullets (brand part no. 4397) bring the same bonded-core construction law enforcement agencies rely on to the reloading bench. Speer’s exclusive manufacturing process bonds the jacket to the core one molecule at a time rather than mechanically crimping the two together, which is why Gold Dot bullets consistently retain close to their full original weight after impact instead of shedding jacket material. That bonded construction is built to deliver immediate, threat-stopping performance for reloaders building personal-protection ammunition, with expansion behavior that stays consistent shot to shot. It’s a proven choice for .40-caliber defensive handloads.
