Winchester Defender .357 Magnum Ammo – 125 Grain Bonded Jacketed Hollow Point Personal Defense Ammunition (20 Round Box)

Winchester Defender .357 Magnum 125 grain Bonded Jacketed Hollow Point ammunition is engineered for maximum terminal performance in high-stakes defensive situations. Designed to meet the demands of the FBI testing protocol, this load delivers the balance of penetration and controlled expansion required for dependable personal protection.

Winchester’s proprietary bonding process welds the copper jacket to the lead core to help prevent separation and promote deeper, more consistent penetration through common defensive barriers. The 125 grain bonded JHP is further enhanced with a notched jacket that is preprogrammed to expand into six uniform segments, supporting reliable expansion up to 1.5 times the original diameter. This combination results in consistent, repeatable tactical performance from a proven defensive revolver cartridge.

Packaged in a 20-round box, Winchester Defender .357 Magnum ammunition is a trusted option for concealed carry revolvers, home defense, and duty use where stopping power and reliability are non-negotiable.
