- Brass Composition: High-quality brass is essential for consistent reloading. Look for brass from reputable manufacturers known for their durability and dimensional consistency.
- Headstamp Identification: Pay close attention to the headstamp, which identifies the manufacturer and often provides clues about the brass's quality and source.
