A bullet puller is a tool used in ammunition reloading to safely remove bullets from cartridge cases. This process is necessary when a reloader wants to adjust the load, reuse the components, or correct mistakes made during the reloading process. Bullet pullers come in various designs, including collet pullers and inertia pullers, each suited for different types of bullets and cartridges. Using a bullet puller helps ensure that the components, such as the bullet, powder, and case, can be reused, reducing waste and saving money. Proper use of a bullet puller is essential for maintaining safety and efficiency in the reloading process.
