Understanding Reloading Dies: The Key to Precise Ammunition
Components of a Reloading Die Set
Reloading dies are precision-engineered tools that shape and size the brass cartridge cases to prepare them for receiving a new bullet, powder charge, and primer. They are essential for consistently producing ammunition that functions reliably and accurately in your firearm. The quality of these dies has a direct impact on your reloading experience.
A typical die set, which is usually sold as a collection, consists of several key components working in concert: the full-length sizing die, the bullet seating die, and often, a crimping die.
The full-length sizing die is usually the first die a reloader encounters. Its primary role is to resize the fired brass cartridge case, bringing it back to the dimensions specified by the cartridge’s design. This process is crucial for ensuring that the loaded round will chamber smoothly in your rifle. As cases are fired, they expand to conform to the chamber of your gun. The full-length sizing die, by compressing and reshaping the case, allows it to fit correctly again. Inside the die, there’s usually an expander that opens up the case neck to the correct diameter to accept the bullet.
For reloaders who want to emphasize precision, neck sizing dies are an option. These dies only size the neck of the case, leaving the rest of the case untouched. They are often used by precision shooters who only fire their cases in one specific rifle. This process extends the life of the brass and can sometimes improve accuracy by allowing the case to perfectly center itself in the chamber. However, if you’re using the same ammunition in multiple rifles or a lever action, a full-length sizing die is usually the best choice.
The bullet seating die performs exactly what its name suggests: it seats the bullet into the case. This die ensures the bullet is pushed to the desired depth within the case, a measurement known as the overall cartridge length. Precise seating depth is critical for accuracy; too deep or too shallow, and your accuracy can suffer. Seating dies often incorporate features that help align the bullet with the case mouth, minimizing runout (the amount the bullet wobbles) and thus optimizing concentricity, also a critical factor for achieving precise shots.
The crimping die, or a crimping stage integrated into the seating die, is often used, and is a feature particularly valuable for the .35 Remington because of its common use in lever-action rifles. The crimp secures the bullet within the case, helping to prevent it from being pushed back into the case during recoil, and promoting more consistent ignition of the powder. Crimping is especially critical in tubular magazine rifles because the bullets in the magazine touch each other. The crimp prevents the bullet from moving under recoil and setting off other rounds.
Materials and Construction: The Foundation of Performance
The materials used in the construction of 35 Rem reloading dies play a significant role in their durability, precision, and ease of use. High-quality dies are often made from hardened steel, which provides excellent wear resistance and dimensional stability. Carbide dies, which incorporate a carbide insert in the sizing die, are another option. Carbide is an incredibly hard and durable material that reduces friction and helps prolong the life of the die. Carbide dies can also eliminate the need for case lubrication during sizing, making the reloading process a little easier and quicker.
The internal finish of the dies is also crucial. A smooth, polished finish minimizes friction, reduces the chance of case damage, and promotes more consistent case sizing. The precision with which the dies are manufactured is another key factor. Dies with tight tolerances and precise dimensions will produce more accurate and consistent results. Look for dies that are manufactured using high-quality materials and processes, and that have a reputation for precision and reliability.
Key Considerations for Choosing Your Dies
Selecting the right 35 Rem reloading dies requires careful consideration of several factors, ultimately influencing the quality of the ammunition you produce.
Brand reputation and quality are paramount. Respected manufacturers invest in quality materials and manufacturing, creating dies that consistently deliver accurate and durable performance. When searching for 35 Rem reloading dies it pays to do your research. Read reviews, talk to other reloaders, and consider the manufacturer’s track record.
The type of die you choose, whether full-length sizing or neck sizing, will significantly influence your reloading process and the end result. For most .35 Remington users, particularly those who load for multiple rifles or use lever actions, the full-length sizing die is the most appropriate choice. It resizes the entire case, ensuring that the loaded round will chamber smoothly in any firearm. Neck sizing is a better choice for those who reload for bolt-action rifles and who want to get the most life out of their brass and squeeze every bit of accuracy.
Proper case preparation is also key. This involves cleaning, trimming, and chamfering the case mouths. Ensure your cases are clean and free of debris, trim the case to the correct length, and chamfer the case mouths to facilitate bullet seating. Regular case trimming is essential. Use a case trimmer that is designed for the 35 Rem cartridge and follow the manufacturer’s recommendations.
Bullet seating and crimping are critical. Accurate seating depth is achieved by using a bullet seating die, and it is essential to achieve consistency. A consistent crimp, is beneficial for bullet retention and consistent ignition, especially with cartridges like the .35 Remington. Always follow the manufacturer’s guidelines for setting the crimp. A proper crimp will ensure that the bullet is securely held in place.

Troubleshooting Common Issues
Even with high-quality dies, reloaders may encounter a few common issues. Knowing how to address them will make your reloading process much smoother.
Stuck cases are a frustrating issue. They are usually caused by improper lubrication or using a sizing die on dirty cases. To prevent this, always lubricate your cases properly before sizing them, and be sure to clean the cases thoroughly. If a case does get stuck, you may be able to use a stuck case remover tool. Follow the manufacturer’s instructions carefully.
Case distortion occurs when the case is deformed during the resizing process. Over-lubrication and aggressive sizing can sometimes be the cause of this. Using the correct type and amount of lubrication and adjusting your sizing die will help.
Bullet seating problems include bullets that are not seated straight. This often results from an out-of-square case mouth or from using too much pressure. Inspect your equipment to ensure all is in good condition.
Consistent crimping issues can happen if the crimping die is not adjusted properly. Make sure to check your crimp is correct, and the die is adjusted to give the correct amount of crim.
