Federal Primers #200 Small Pistol Magnum (Box of 5000)

Small Magnum Pistol primers are a type of primer used in reloading ammunition for handguns. Here are some key notes on small Magnum Pistol primers:

Definition:

• Small Magnum Pistol Primers are designed to provide a hotter flame and higher pressure than standard small pistol primers. They are specifically intended for use with magnum loads and can be beneficial for certain high-performance cartridges.

Characteristics:

• Size: They have the same dimensions as standard small pistol primers but are formulated to produce a stronger ignition.
• Composition: Typically contain a different chemical mix in the primer compound to achieve higher temperatures and pressures.

Applications:

• Cartridges: Commonly used in magnum pistol cartridges such as .357 Magnum, .40 S&W (in certain loadings), and .44 Magnum.
• Load Development: Useful for loads that require consistent ignition, especially with slower-burning powders that may need a stronger spark to ignite properly.

Considerations:

• Interchangeability: Small Mag Pistol primers should not be substituted for standard small pistol primers without careful consideration, as they can produce higher pressures. Always consult load data specific to the primer being used.
• Pressure Sensitivity: Using mag primers in standard loads can increase pressure significantly, potentially leading to unsafe conditions.
• Reloading Data: Always refer to reloading manuals or manufacturer recommendations when using small magnum primers, as they may require adjustments to powder charges.

Advantages:

• Improved Ignition: Better ignition reliability, especially in cold weather or with difficult-to-ignite powders.
• Consistency: Can help achieve more consistent velocities and accuracy in magnum loads.

Disadvantages:

• Increased Pressure: The increased ignition strength can lead to overpressure situations if not accounted for in load development.
• Cost: Typically more expensive than standard primers, which can be a consideration for high-volume reloaders.

Conclusion:

Small Mag Pistol primers are a valuable tool for reloaders looking to develop high-performance loads for magnum cartridges. However, they must be used with caution and an understanding of their effects on pressure and performance. Always prioritize safety and consult reliable reloading data when incorporating them into your ammunition.
