Winchester Defender 10mm is a 180-grain bonded jacketed hollow point load for personal defense, sold in a 20-round box. The bonding joins the jacket to the lead core to help retain weight, and the hollow point promotes controlled expansion. The listed muzzle velocity is 1,240 feet per second, and the casing is nickel-plated brass for feeding and extraction.

The bonded 180-grain load is built for a 10mm handgun used in personal defense. A Maine owner who keeps a 10mm pistol at home or carries one will find a 20-round box a convenient size for storage. Confirm the pistol is chambered for 10mm before loading. The bonded bullet and nickel-plated brass casing are the features the supplier highlights for weight retention and reliable feeding.
