Best Practices for Reloading Controlled Expansion Bullets Safely?

Choosing the Right Equipment

When reloading controlled expansion bullets, you’ll need a dedicated press for expanding bullets, such as a Lee Auto-Disk Bullet Reloader or a Dillon XL 750. These presses are designed with safety features and precision dies to minimize the risk of accidental expansion or case deformation. Always use a new, clean shell holder and a die specifically designed for expanding bullets, and follow the manufacturer’s instructions for assembly and use.

Safety Precautions and Techniques

When reloading controlled expansion bullets, never over-heat the bullet or the case, as this can cause the bullet to become deformed or the case to become brittle. Always follow a consistent reloading procedure, including weighing the powder charge and checking the case headspace. If a bullet becomes stuck in the die, use a bullet puller to carefully remove it, taking care not to damage the case or the die. Keep the work area well-ventilated, and avoid inhaling the dust and debris generated by the reloading process.

Best Practices for Bullet Expansion

When expanding controlled expansion bullets, always use a consistent expansion ratio to ensure consistent performance. Aim for an expansion ratio of 1.2 to 1.5, and use a die specifically designed for expanding bullets to achieve this ratio. Always check the bullet for proper seating and expansion before loading it into a case, and use a caliper or micrometer to ensure the bullet is seated to the correct depth.
