Reloading Dies
Reloading dies are crucial for the reloading process. These dies are threaded into the reloading press and perform various functions, including resizing the case, seating the bullet, and crimping the case. A set of dies will typically include a resizing die, a seating die, and a crimping die.
Case Trimmer
A case trimmer is used to maintain consistent case length. This is essential for accuracy and proper chambering.
Scales and Powder Measure
Scales and a powder measure are essential for accurately dispensing powder charges. A digital scale offers excellent precision and makes powder measuring simple and fast.
Priming Tool
A priming tool is used to seat the primer into the primer pocket. This can be a hand-held tool or incorporated into your reloading press.
Case Cleaning Equipment
Case cleaning equipment is important for preparing the cases for use. Cleaning brass removes carbon buildup and residue from the brass cases, making the process safer and more efficient. This includes tumblers, sonic cleaners, and other types of equipment.
300 Blackout Components
Brass Cases: Start with quality brass cases. Consider buying new brass, especially when starting. Alternatively, you can use fired cases, which require proper cleaning, resizing, and inspection before reloading. Reputable brass brands are highly recommended.
