The Winchester .25-20, a classic cartridge with a rich history, continues to attract reloaders seeking to experience its unique ballistics and nostalgic appeal. Finding the right reloading dies is crucial for safe and accurate reloading, ensuring your spent brass is transformed into reliable ammunition. This guide will navigate you through the process of selecting and using .25-20 reloading dies.
Understanding Reloading Dies and Their Importance
Reloading dies are precision tools used to resize, deprime, and prime cartridge cases, and seat bullets. They are essential for ensuring consistent and safe ammunition. Choosing the right dies for your .25-20 caliber is paramount to the success and safety of your reloading efforts. Improperly sized cases can lead to dangerous pressure increases within the firearm.
Types of Reloading Dies
Several sets of dies are available, each offering different features and functionalities:
-
Full-Length Sizing Dies: These dies resize the entire case, including the neck and body, returning the brass to its original dimensions. This is often necessary for the first resizing after firing.
-
Neck Sizing Dies: These dies only resize the neck of the cartridge case, leaving the body untouched. This helps to maintain case neck tension, improving accuracy and reducing wear on the brass. Neck sizing is generally preferred for subsequent reloads, after the initial full-length sizing.
-
Bullet Seating Dies: These dies seat the bullet to the correct depth within the case. Accurate bullet seating is critical for consistent bullet velocity and accuracy.
-
Decapping Dies: These dies remove the spent primer from the cartridge case, preparing it for the new primer. Often incorporated into the sizing die.
-
Seating & Crimping Dies: A combination die handling both bullet seating and crimping of the case mouth onto the bullet, improving bullet retention.
Choosing the Right Winchester .25-20 Ammo Dies
When selecting .25-20 reloading dies, several factors must be considered:
-
Manufacturer: Reputable manufacturers like RCBS, Lee Precision, Hornady, and Redding are known for producing high-quality dies. Each brand has its strengths, often involving die construction materials and design features.
-
Die Set Completeness: Consider whether you need a complete set including sizing, decapping, bullet seating, and possibly crimping dies, or if you only need individual dies to supplement an existing set.
-
Compatibility: Ensure the dies are specifically designed for the .25-20 Winchester cartridge. Using incorrect dies can lead to damaged brass and unsafe ammunition.
-
Your Reloading Press: The dies must be compatible with the type of reloading press you own (e.g., single-stage, progressive). The press's shell holder must also be compatible with the .25-20 case.
Sourcing Your .25-20 Ammo Dies
You can typically find .25-20 reloading dies at:
-
Online Retailers: Major online retailers specializing in reloading supplies carry a wide selection of dies from various manufacturers.
-
Local Gun Shops: Many local gun shops stock reloading supplies, including dies. This allows for direct consultation with experienced staff.
-
Specialized Reloading Suppliers: Companies focused solely on reloading equipment often offer a wider selection and specialized dies for less common calibers like the .25-20.
Beyond the Dies: Essential Reloading Supplies

- Reloading Press: The machine that powers the reloading process.
- Case Prep Tools: Tools for cleaning, lubricating, and preparing brass cases.
- Powder Measure: For accurately dispensing propellant.
- Scale: A precise scale for weighing powder charges.
