Choosing the right reloading dies for your 9mm ammunition is crucial for consistent, accurate, and safe results. With numerous brands and styles available, navigating the options can feel overwhelming. This guide will break down the key factors to consider and highlight some top contenders for best 9mm reloading dies, catering to both beginners and experienced reloaders.
Factors to Consider When Choosing 9mm Reloading Dies
Before diving into specific die sets, let's examine the crucial factors influencing your decision:
1. Die Set Type:
- Full-Length Sizing Dies: These dies resize the entire cartridge case, including the neck and body. Ideal for new brass or cases that have been significantly deformed. They require more force to operate.
- Neck Sizing Dies: These dies only resize the neck of the cartridge case, preserving the body dimensions. This gentler approach minimizes case wear, leading to longer brass life, but it's suitable only for cases that are already within acceptable dimensions.
- Bullet Seating Dies: This die is used to seat the bullet to the desired depth. While sometimes sold separately, they are usually part of a reloading die set.
- Crimping Dies: This die secures the bullet in the case mouth, preventing bullet setback during firing and transportation. Crimping is often a separate process and may require a separate die or stage within a progressive press setup.
2. Brand Reputation and Quality:
Several reputable manufacturers produce high-quality 9mm reloading dies. Look for brands known for their precision, durability, and customer service. Some popular choices include:
- Lee Precision: Known for their affordability and user-friendly designs, Lee dies are excellent for beginners.
- RCBS: A long-standing brand recognized for its precision and quality, RCBS offers a range of dies to suit different skill levels and preferences.
- Hornady: Hornady dies are appreciated for their consistent performance and are a popular choice among both casual and serious reloaders.
- Dillon Precision: Famous for its progressive reloading presses, Dillon also manufactures high-quality dies, renowned for their precision and durability.
3. Features and Adjustments:
Consider features like:
- Micrometer Adjustments: Allow for incredibly precise adjustments, particularly beneficial for fine-tuning bullet seating depth.
- Case Length Adjustment: Ensures proper case length for reliable feeding and chambering.
- Expander Ball: This part of the sizing die helps expand the neck of the case for smooth bullet seating.
4. Your Reloading Press:
Ensure that the dies you choose are compatible with your reloading press. Dies are typically available in 7/8"-14 or 1/2"-20 threads, which are common sizes in reloading presses.

Beyond the Dies: Important Considerations

Invest in accurate scales for measuring powder charges, and ensure your reloading press is properly set up and maintained.
Accurate and safe reloading requires attention to detail, practice, and a commitment to safety. Start with a reliable die set, follow instructions meticulously, and gradually develop your skills. Happy reloading!
