The .45-70 Government cartridge, a legendary round with a rich history, demands precision reloading for optimal performance. Choosing the right dies is crucial, and RCBS, a respected name in reloading equipment, offers a range of options to meet the needs of both novice and experienced reloaders. This guide dives deep into RCBS 45-70 dies, exploring their features, benefits, and considerations to help you make an informed decision.
Understanding RCBS Die Sets
RCBS offers various .45-70 die sets, catering to different preferences and reloading styles. Most sets include the essential dies:
-
Sizing Die: This die reduces the diameter of the fired brass case to its original dimensions, preparing it for the subsequent steps. RCBS sizing dies are known for their robust construction and precise sizing capabilities. Consider whether you need a full-length sizing die or a neck sizing die, depending on your reloading goals and brass condition. Full-length sizing is generally used for new brass or when significant case deformation needs correction. Neck sizing is typically preferred for subsequent reloads to minimize brass wear and maintain accuracy.
-
Powder Die: This die accurately measures and dispenses the correct amount of powder into each cartridge case. RCBS powder dies are designed for consistent powder drops, contributing to the overall precision of your reloading process. Proper powder measure calibration is crucial for safety and accuracy.
-
Seating Die: This die seats the bullet into the cartridge case, ensuring proper bullet alignment and overall cartridge length. RCBS seating dies provide precise bullet seating depth adjustment, a crucial factor in achieving optimal accuracy. This die often incorporates a crimp function as well.
-
Optional Dies: Some RCBS sets include additional dies like a crimping die, which helps secure the bullet and prevent it from moving during firing. Crimp dies are very important in .45-70, where proper bullet seating and crimping are critical.
Choosing the Right RCBS 45-70 Die Set
The best RCBS 45-70 die set for you will depend on your specific needs and reloading experience:
For Beginners:
A complete set including sizing, powder, and seating dies is recommended. The inclusion of a factory crimp die is a good starting point, but learning to adjust crimp settings correctly is very important.
For Experienced Reloaders:
Experienced reloaders may opt for individual dies to customize their setup or replace worn components. They may also choose specialized dies like a neck sizing die or a separate crimp die to fine-tune their process.
Key Features and Benefits of RCBS Dies
RCBS dies are renowned for several key features:
-

Reloading Press: A sturdy press, such as a Rock Chucker Supreme, is crucial for applying consistent pressure during the reloading process.
-
Case Prep Tools: Trimming, deburring, and cleaning tools maintain brass consistency, improving efficiency and reloading success.
-
Scale: An accurate powder scale is vital for consistent powder charges and safe reloading practices.
-
Bullet Puller: A bullet puller is invaluable for correcting mistakes or recovering bullets for reuse.
