Lee Precision .38 Special Carbide 3-Die Set (Silver) (90510)
The Lee Precision 90510 set includes a carbide full-length sizing die, a universal seating die, and a powder-through expanding die, plus an accompanying universal shell holder and powder dipper. The carbide construction promotes long life and smooth resizing, helping maintain consistent case dimensions for reliable chambering.

This makes it a practical, all-around option for 38 Special and occasional 357 Magnum reloads.

Colored Smart Lock bushings help identify dies at a glance, which speeds up setup in busy reloading sessions. The carbide sizing die provides durable, consistent resizing, while the expander improves neck tension and seating uniformity. This combination supports accurate reloads for both 38 Special and 357 Magnum with reliable chambering.
Redding Reloading Three Die Set, 38 Special/357 Magnum (80184)
The Redding 80184 die set features a full-length resizing die, a separate expander die, and a conventional seating die. The expander uses an expanding plug to prepare case necks for optimal bullet fit, promoting uniform seating and improved overall ammo consistency. Redding dies are machined to tight tolerances and heat-treated for longevity, supporting dependable performance across reload sessions. This set is well-suited for shooters who value precise neck expansion and durable construction.

The Hornady Series II 3-Die Set includes a size die, expander die, and seating die, designed for the most popular handgun cartridges. Precision machining supports accurate reloading, delivering consistent neck expansion and seating. While labeled for 38 Super Auto, these dies are compatible with related straight-wall pistol cartridges and maintain tight tolerances for dependable performance in 38 Special reloads when used with appropriate dies and adapter configurations.
90861 Lee Precision, Carbide Factory Crimp Die, .38 Special
The 90861 Carbide Factory Crimp Die is designed to size and crimp in a single stroke for 38 Special and 357 Magnum, ensuring that crimps do not prevent chambering, and that each round feeds reliably in the firearm. The carbide construction provides durability, and the combined sizing and crimping operation streamlines the reloading process. This die is particularly helpful for shooters seeking consistent neck crimps and smooth chambering in straight-wall cases.
REDDING Reloading Pro Series Die Set Straightwall 38 Special/357 Magnum
The Redding Pro Series Die Set is optimized for progressive loading machines, featuring a streamlined configuration that supports efficient case processing without redundant steps. It includes an NXGEN carbide sizing die for smooth, precise resizing of straight-wall cases, improving case life and uniformity. The pro-series seating die has a wide-entry design for fast, reliable bullet alignment without crimping to preserve station flexibility, making it a strong choice for higher-volume loading scenarios.
Buying Guide: Key Purchase Considerations And Comparisons
- Caliber compatibility: If you shoot both 38 Special and 357 Magnum, choose a die set that covers both, or plan for a dedicated set per caliber to simplify setup.
- Die types and functions: Full-length sizing, expander, seating, and crimping actions impact accuracy and fit. Carbide dies offer longevity and smoother resizing, reducing maintenance between reloads.
- Progressive vs single-stage: Progressive systems increase throughput but require careful setup. For hobby shooting, a reliable 3-die set on a single-stage press may suffice; for high-volume practice, consider progressive-friendly options like the Pro Series.
- Neck expansion and seating uniformity: A quality expander die improves neck tension consistency, which stabilizes bullet seating and pressure control. Look for dies with tight tolerances and smooth seating features.
- Durability and materials: Carbide dies last longer and resist wear, especially with frequent reloading. Steel dies may be adequate for occasional use but can require more frequent resizing tweaks.
- Ease of setup: Sets with color-coded bushings or breech-lock systems help identify dies quickly, reducing setup time during sessions.
- Kit completeness: Some sets include shell holders or dippers, which can streamline initial setup. Confirm what is included to avoid purchasing missing components separately.
- Accuracy and tolerance: Look for manufacturer specifications about tolerances and heat treatment. Tighter tolerances generally translate to more consistent ammunition.
- Budget vs reliability: While price matters, prioritize consistent performance, especially if you reload regularly for practice or competition.
- Safety and standards: Ensure dies are designed for standard straight-wall cartridges, with proper neck sizing and crimping features to prevent over-crimping and jams.
