The RCBS Rock Chucker Supreme Master Reloading Press is a legend among reloaders, known for its durability and precision. However, like any mechanical device, it requires occasional maintenance and may need parts replaced over time. This guide will cover common RCBS Rock Chucker parts, troubleshooting, and where to find replacements. Understanding your press's components is key to ensuring safe and efficient reloading.
Common RCBS Rock Chucker Parts and Their Functions
The RCBS Rock Chucker, despite its robust design, has several key components that can wear out or require replacement. Let's break down some of the most frequently replaced parts:
1. Ram:
The ram is the heart of the press, responsible for transferring force from the handle to the shell plate. Wear and tear can cause it to become loose or damaged. Look for signs of scratches, bending, or excessive play.
2. Shell Holder:
Shell holders are specific to the cartridge type you're reloading. They hold the cartridge case securely during the resizing and priming processes. Over time, these can become worn or damaged, leading to inconsistent results or even case damage.
3. Handle:
The handle itself is surprisingly robust, but the threads or the handle attachment can wear out with extended use. A loose or damaged handle can be a safety hazard.
4. Locking Ring:
This ring secures the die to the press. A damaged or stripped locking ring will prevent you from properly securing the die, leading to potential accidents.
5. Dies:
While not strictly a part of the press itself, dies are crucial components of the reloading process. Over time, dies can become worn, requiring replacement to maintain accuracy and prevent case damage. This includes resizing dies, seating dies, and powder measure dies.
Troubleshooting Common RCBS Rock Chucker Issues
Before ordering replacement parts, it's important to properly diagnose the issue. Here are some common problems and potential solutions:
1. Binding or Sticking:
This often points to a lubrication issue. Regular lubrication with a high-quality reloading lubricant is crucial. Also, check for any debris or buildup on the ram or other moving parts.
2. Loose or Wobbly Components:
Examine all parts for signs of wear. Tighten any loose screws or bolts. If the issue persists, a replacement part might be necessary.
3. Inconsistent Results:
Inconsistent results, like improperly seated primers or inconsistent powder charges, often indicate worn dies or a damaged shell holder.
4. Difficult Handle Operation:
This can stem from worn ram components or a lack of lubrication. Check for any binding or obstructions.

Finding replacement parts for your RCBS Rock Chucker is generally straightforward. RCBS offers a comprehensive parts catalog, and many online retailers specializing in reloading supplies stock these parts. When ordering, always specify the exact model number of your press to ensure compatibility. It's also a good idea to keep a small stock of common wear parts on hand to avoid delays.
Maintaining Your RCBS Rock Chucker for Optimal Performance
Regular maintenance is key to extending the lifespan of your press. This includes regular lubrication, cleaning, and visual inspection for wear and tear. A little preventative maintenance can go a long way in avoiding costly repairs.
By understanding the common parts of your RCBS Rock Chucker and performing routine maintenance, you can ensure years of safe and reliable reloading. Remember, proper reloading technique and equipment maintenance are paramount for safe and accurate ammunition production.
