Technical Specifications
Federal #200 primers are classified as small pistol magnum primers, making them ideal for cartridges that require additional ignition energy. The #200 designation indicates Federal’s specific magnum pistol primer formulation. These primers measure approximately 0.175″ in diameter and are compatible with standard small pistol primer pockets.
Application Guide
These magnum primers are specifically designed for:
- 9mm Luger (especially +P and +P+ loads)
- .357 Magnum and .357 SIG
- .44 Magnum
- 10mm Auto
- .40 S&W (with appropriate load data)
- Other magnum pistol cartridges requiring small pistol primers
Important Safety Note: Always consult current reloading manuals and reduce powder charges when switching from standard to magnum primers. Magnum primers generate more heat and flame, which can increase pressure if not properly accounted for in your load development.
