Winchester® Defender was chosen by the FBI as their primary service round. It’s engineered to maximize terminal ballistics, as defined by the demanding FBI test protocol, which simulates real-world threats. Winchester’s proprietary bonding process welds the lead core and copper jacket together to obtain controlled expansion and higher weight retention. That means better stopping power when it counts.
