The 5.7x28mm cartridge, known for its high velocity and flat trajectory, has gained popularity among enthusiasts for both target shooting and personal defense. Reloading your own 5.7x28mm ammunition offers significant cost savings and allows for precise customization to your specific needs. This guide provides comprehensive reloading data using Hodgdon powders, emphasizing safety and accuracy. Always consult the latest Hodgdon reloading manual before attempting any reloading. This information is for guidance only and should not be considered a substitute for the official manual.
Understanding the 5.7x28mm Cartridge
The 5.7x28mm is a bottlenecked cartridge designed for high velocity and accuracy. Its small size and relatively lightweight projectile contribute to its unique performance characteristics. This also means that proper reloading techniques are crucial to ensure safety and optimal performance. Incorrect loads can lead to dangerous pressure spikes and potential firearm damage.
Choosing the Right Hodgdon Powder
Hodgdon offers several powders suitable for the 5.7x28mm cartridge. The best choice will depend on your specific bullet weight and desired velocity. Some popular options include:
-
Hodgdon Lil' Gun: Known for its high energy density, Lil' Gun can provide excellent velocity with lighter bullets. However, it's crucial to meticulously follow the recommended load data due to its potential for high pressure.
-
Hodgdon CFE Pistol: A versatile powder offering good accuracy and consistent performance across a range of bullet weights. It often provides a more moderate pressure curve compared to Lil' Gun.
-
Hodgdon Universal Clays: While not always the top choice for maximum velocity in the 5.7x28mm, Universal Clays is excellent for producing reliable loads with good accuracy, particularly when working with heavier bullets.
Note: This is not an exhaustive list, and other Hodgdon powders might also be suitable. Always refer to the latest Hodgdon reloading manual for the most up-to-date and comprehensive data.
