Within the world of reloading, the choice of dies is fundamental to success. One of the most accessible and valued options for 45-70 reloaders is the Lee Precision die set. This article delves deep into the world of Lee 45-70 Dies, offering a comprehensive guide to help you achieve accurate, consistent, and satisfying reloading results.
The Players in the Reloading Game: The Components of Lee 45-70 Die Sets
Understanding the different types of dies available in a Lee 45-70 Dies set is essential for effective reloading. Let’s explore the functions of each die:
Shaping the Brass: Full-Length Sizing Die
The full-length sizing die is the first step in the reloading process after the spent primer has been removed. Its primary purpose is to reshape the fired brass case back to its original dimensions. This process is crucial for ensuring the reloaded cartridge fits properly in the chamber of your rifle. The full-length sizing die will push the brass back to factory spec. This is especially important if you use multiple rifles or a lever action, where the brass may not fit well after firing. This is very beneficial if the rifle’s chamber is worn. The Lee full-length sizing die features a unique design with a self-centering action, which helps to align the case during the sizing process.
Preserving Brass Life: Neck Sizing Die
For reloaders who primarily shoot a single rifle, a neck sizing die can be an excellent option. Instead of sizing the entire case, the neck sizing die only resizes the neck of the brass. This allows the brass to maintain its shape near the base. This provides less stress on the brass during resizing. This can extend the brass life, and can also improve accuracy. The neck sizing die is especially useful if you’re loading for precision shooting, as it can minimize case runout and improve bullet alignment.
Precisely Placing the Projectile: Seating Die
The seating die is responsible for carefully seating the bullet into the resized case. This process requires precision to ensure the bullet is seated to the correct depth, which is critical for both accuracy and safe operation. The Lee seating die offers an adjustable seating depth feature, allowing you to fine-tune the overall cartridge length (OAL) to match your rifle’s chamber and the specific bullet you’re using. The adjustable seating depth makes for a lot of versatility. This feature allows for tailoring your rounds for maximum accuracy. Lee’s seating die also often includes a bullet seater alignment feature to minimize any misalignment during seating.
The Finishing Touch: Crimping Die
Depending on the specific set you choose, your Lee 45-70 Dies set may include a crimping die. A crimp, most commonly a roll crimp in 45-70, is applied to the case mouth after the bullet has been seated. This critical step serves several purposes: it helps to secure the bullet in the case, prevent bullet setback during recoil, and can contribute to more consistent burn rates of the powder. A good crimp ensures that the bullet stays in place.
The Making of a Durable Reloading Tool: Materials and Design of Lee 45-70 Dies
Lee Precision dies are constructed with quality materials and an efficient design. The dies are typically made from steel. Steel provides durability and longevity. The robust construction ensures your dies can withstand years of use. Lee’s streamlined manufacturing processes contribute to keeping costs down. The end product is a set of dies that deliver excellent performance without breaking the bank.
Key Features: The Lee Advantage
Lee 45-70 Dies boast several features that contribute to their value. Their design also contributes to ease of use. The full-length sizing die often incorporates a self-centering feature, simplifying the case alignment. The seating die’s adjustable depth provides versatility in bullet seating. Lee’s commitment to value allows reloaders to enjoy great performance without high prices.
The Reloading Dance: A Step-by-Step Guide to Using Your Lee 45-70 Dies
Now, let’s explore the practical application of your Lee 45-70 Dies! Here’s a detailed guide:
Setting the Stage: Preparing Your Workspace
Before beginning, assemble your reloading equipment. You’ll need a reloading press, a case trimmer, a scale, a primer seating tool, and any tools for cleaning brass. Ensure a clean, well-lit workspace. Safety first!
The Brass Shaping Act: The Full-Length Sizing Process (or Neck Sizing)
- Lubricate: Apply case lubricant (follow the manufacturer’s instructions).
- Insert: Place the case into the shell holder and raise it into the full-length sizing die.
- Size: Lower the ram of the press, forcing the case into the die. This reshapes the case.
- Extract and Inspect: Remove the sized case and inspect it for any signs of damage.
- Neck Sizing (if applicable): Follow the same steps with the neck sizing die, if you have chosen this method.
- Clean Lubricant: Remove any case lubricant.
Cleaning and Setting the Table
Always clean the brass before moving on. Cleaned brass provides a good base to work on. After sizing, clean the brass to ensure all lubricant is removed.
Preparing the Case for the Round: Priming
Priming can be done separately. Make sure the primer is fully seated in the primer pocket.
The Powdery Alchemy: Powder Charging
- Measure: Using your scale and powder measure, carefully dispense the recommended powder charge for your chosen bullet and load data. Always adhere to the load data found in reliable reloading manuals!
- Pour: Pour the powder into the case.
- Inspect: Check each case to make sure that each case contains the correct powder amount.
The Bullet Seating Ritual
- Insert Bullet: Place the bullet onto the case mouth.
- Seat: Raise the case into the seating die. Lower the ram of the press to seat the bullet to the desired depth.
- Measure: Verify the overall cartridge length (OAL) with calipers to ensure it matches your specifications.
The Crimp Finale (if using a crimp die)
- Adjust Die: Set the crimping die according to the manufacturer’s instructions.
- Crimp: Raise the loaded cartridge into the crimping die and crimp.
- Inspect: Inspect the crimp for consistency and proper application.
Final Examination and Verification
Check each completed round for any irregularities. Weigh each completed round.
Troubleshooting the Reloading Process
Sticking Cases
If a case sticks in the die, ensure you’re using adequate lubricant.
Inconsistent Seating Depth
Ensure the seating die is set up properly. Measure the length of the rounds.
Crimping Issues
Adjust the crimping die until you achieve the desired crimp.
Tips and Tricks for Excellence
The Essence of Smoothness: Lubrication for Success
Proper lubrication is essential for smooth reloading. Always use a suitable case lubricant, following the manufacturer’s instructions. Over-lubrication can cause dents, so use it sparingly.
Precision is Key: Case Preparation is Critical
Prepare your brass. Trimming and deburring the case mouth ensures consistency.
The Foundation of Safety and Performance: Reloading Data
Always consult a reputable reloading manual and follow the recommended load data for your components. Start with the starting loads, and then gradually increase the charge, while watching for pressure signs.
