Description

Winchester WSP Small Pistol Primers deliver consistent ignition performance for handgun cartridges ranging from .380 ACP to .45 ACP. These non-corrosive primers feature Winchester's proven cup design and priming compound formulation that ensures reliable ignition across temperature extremes.

What Makes This Different

Winchester's WSP primers use a softer cup construction compared to magnum primers, optimized specifically for standard pressure handgun loads. The priming compound burns cleaner than many alternatives, reducing fouling buildup in firing pins and bolt faces. Each primer undergoes individual inspection during manufacturing, maintaining lot-to-lot consistency that competitive shooters and reloaders depend on for uniform velocities.

Key Features

Non-corrosive priming compound prevents barrel and case damage
Standard brisance level ideal for powders like Bullseye, Unique, and HP-38
Consistent cup thickness ensures uniform firing pin indentation
Temperature stable from -40°F to 140°F operating range
Compatible with all standard small pistol cartridge cases
Individual primer inspection maintains quality control standards
Packaged in protective plastic trays preventing damage during shipping

These primers perform reliably in competition environments where consistent ignition timing affects accuracy. Law enforcement agencies specify Winchester primers for duty ammunition due to their proven reliability record. The moderate sensitivity level reduces slam-fire risks in semi-automatic pistols while maintaining positive ignition with lighter firing pin springs. Hunters loading reduced-velocity rounds for small game appreciate the consistent low-temperature performance.
