What Makes This Different

Winchester's large pistol primers feature a carefully formulated priming compound that produces uniform flame spread and consistent pressure curves. The brass cups undergo precision manufacturing to ensure proper fit in primer pockets while maintaining the structural integrity needed for magnum loads. These primers ignite reliably even with compressed powder charges and heavy bullets that require higher ignition energy.

Key Features
