My Buying Guides on Set Up 50Ae Rcbs 4 Dies Setup Instructions
When I first decided to set up my RCBS 4-die set for the .50 AE (Action Express) cartridge, I realized having a clear, step-by-step guide was essential. Whether you’re new to reloading or just picking up this specific die set, I want to share my experience and tips to help you get started smoothly.
Understanding What’s Included in the RCBS 4-Die Set
Before diving into setup, I made sure I knew exactly what comes in the set. Typically, the RCBS 4-die set for .50 AE includes:
- Full-Length Sizing Die: Resizes the spent brass to proper dimensions.
- Expanding Die: Prepares the case mouth to accept a new bullet.
- Seating Die: Seats the bullet to the correct depth.
- Crimping Die: Applies a crimp to hold the bullet firmly in place.
Knowing these parts helped me understand the sequence and purpose of each step.
Preparing Your Workspace and Equipment
I always start by cleaning my brass and making sure my press is securely mounted. Having a clean, organized bench with proper lighting and safety gear makes the process more enjoyable and efficient.
Step 1: Installing the Full-Length Sizing Die
I screwed the full-length sizing die into the press’s die holder until it just touched the shell holder with a cartridge inside. Then, I backed it off slightly (about a quarter turn) to avoid over-sizing. This step ensures the brass returns to the correct dimensions while retaining the proper neck tension.
Step 2: Setting Up the Expanding Die
Next, I installed the expanding die. This die flares the case mouth slightly, making it easier to seat a bullet without shaving lead. I adjusted it so that the expander ball just enters the case mouth without excessive force.
Step 3: Seating the Bullet
The seating die needs to be set to seat bullets to the proper overall length (OAL). Using my calipers, I measured the recommended OAL for the .50 AE cartridge and adjusted the die accordingly. I ran a few test rounds, adjusting incrementally until I was confident the bullets were seated straight and at the right depth.
Step 4: Applying the Crimp
Finally, the crimp die helps secure the bullet in place, which is crucial for consistent ignition and safe pressure levels. I adjusted the crimp die until I achieved a firm crimp without deforming the bullet or case.
Additional Tips From My Experience
- Use a Shell Holder Designed for .50 AE: This ensures proper alignment during resizing.
- Lubricate Cases if Needed: If your brass is tight in the sizing die, a light application of case lube prevents sticking.
- Check Each Step with Calipers: Measuring dimensions throughout helps avoid issues like over-sizing or seating too deep.
- Refer to RCBS Manuals: The official instructions are always a great reference alongside hands-on adjustments.
Final Thoughts
Setting up the RCBS 4-die set for .50 AE can seem intimidating at first, but breaking it down into clear steps made it manageable for me. With patience and careful adjustments, you’ll have consistent, reliable reloads that enhance your shooting experience. I hope my guide helps you get started confidently!
