Introduction to RCBS 45-70 Carbide Dies
The world of ammunition reloading is a fascinating one, offering firearm enthusiasts the opportunity to create custom loads tailored to their specific needs. Among the various calibers available for reloading, the .45-70 Government cartridge holds a special place in the hearts of many shooters. This powerful round, with its rich history dating back to the late 19th century, continues to be popular among hunters and target shooters alike. When it comes to reloading the .45-70, RCBS stands out as a leading manufacturer of high-quality reloading equipment, including their renowned carbide dies.
Understanding RCBS 45-70 Carbide Dies
RCBS 45-70 carbide dies are precision-engineered tools designed to make the reloading process more efficient and accurate. These dies are typically sold in sets of three, each serving a specific purpose in the reloading process:
1. Sizing Die: This die resizes the fired brass case to its original dimensions and removes the spent primer.
2. Expander Die: It expands the case mouth to the proper diameter for accepting a new bullet.
3. Seating Die: This die seats the new bullet to the correct depth and can also apply a crimp if desired.
The use of carbide in these dies offers several advantages over traditional steel dies:
- Increased durability and longer lifespan
- Reduced need for case lubrication
- Smoother operation and less wear on brass cases
The Reloading Process Using RCBS 45-70 Carbide Dies
Reloading .45-70 ammunition with RCBS carbide dies is a straightforward process that can be broken down into several steps. Let's walk through the process, highlighting the use of RCBS equipment at each stage.
Step 1: Case Preparation
Before beginning the reloading process, it's crucial to inspect your brass cases for any signs of damage or excessive wear. Clean the cases thoroughly and, if necessary, trim them to the correct length. While RCBS carbide dies reduce the need for case lubrication, a light coating of sizing lube can still be beneficial, especially for new reloaders.
Step 2: Resizing and Decapping
Insert the sizing die into your reloading press and adjust it according to the manufacturer's instructions. Place a prepared case in the shell holder and raise the press handle to full extension. This action will resize the case to its original dimensions and push out the spent primer. Lower the handle to remove the case.
Step 3: Priming
Using a priming tool or the priming system on your reloading press, insert a new primer into the case. Ensure that the primer is seated flush with or slightly below the case head.
Step 4: Powder Charging
Consult a reliable reloading manual for the appropriate powder type and charge weight for your desired load. Use a powder measure or scale to dispense the correct amount of powder into each case. Double-check the powder charge to prevent under- or over-charging.
Step 5: Bullet Seating
Install the seating die in your press and adjust it to achieve the desired overall length (OAL) for your loaded cartridge. Place a charged case in the shell holder and a bullet on top of the case mouth. Raise the press handle to seat the bullet to the proper depth.
Step 6: Crimping (Optional)
If your load requires a crimp, you can either use the built-in crimping feature of the RCBS seating die or a separate crimping die. Adjust the die to apply the appropriate amount of crimp without deforming the bullet.

Tips for Success with RCBS 45-70 Carbide Dies
To get the most out of your RCBS 45-70 carbide dies and ensure consistent, high-quality reloads, consider the following tips:
1. Always follow the manufacturer's instructions for die setup and adjustment.
2. Start with once-fired brass from a known source to ensure consistency.
3. Keep detailed records of your loads, including components used and performance data.
4. Regularly clean and maintain your dies to ensure optimal performance.
5. Invest in quality measuring tools, such as calipers and a reliable powder scale.
6. Begin with published load data and work up gradually to find the optimal load for your firearm.
7. Join a local reloading club or online community to share knowledge and experiences with fellow enthusiasts.
Conclusion
RCBS 45-70 carbide dies offer reloaders a high-quality, durable solution for crafting precise ammunition. By understanding the reloading process and following best practices, you can create custom loads that maximize the potential of your .45-70 firearm. Whether you're a seasoned reloader or just starting out, investing in quality equipment like RCBS carbide dies can significantly enhance your reloading experience and the performance of your ammunition.
Frequently Asked Questions
Q1: What are the advantages of using carbide dies for reloading .45-70 ammunition?
Answer: Carbide dies offer several advantages, including increased durability, reduced need for case lubrication, smoother operation, and less wear on brass cases. These benefits can lead to more consistent reloads and a more efficient reloading process.
Q2: Do I need to trim .45-70 cases before reloading with RCBS carbide dies?
Answer: While carbide dies can help extend the life of your brass, it's still recommended to check case length periodically and trim when necessary. This ensures consistent overall length and helps maintain proper headspace.
Q3: Can I use RCBS 45-70 carbide dies with other brands of reloading presses?
Answer: Yes, RCBS dies are designed to be compatible with most standard 7/8"-14 thread reloading presses, regardless of brand. Always check the specifications of your press to ensure compatibility.
Q4: How often should I clean my RCBS 45-70 carbide dies?
Answer: It's a good practice to clean your dies after every reloading session or at least every 500-1000 rounds. Regular cleaning helps maintain the dies' performance and extends their lifespan.
Q5: Are RCBS 45-70 carbide dies suitable for both straight-walled and bottleneck cases?
Answer: The .45-70 is a straight-walled case, and RCBS carbide dies are specifically designed for this cartridge type. For bottleneck cases, you would need to use dies designed for those specific calibers.
