Finding the right decapping pin size is crucial for smooth, efficient reloading. Using the incorrect size can lead to damaged cases, frustrating jams, and even potential injury. This guide will help you understand RCBS decapping pin sizes, how to identify the correct one, and troubleshoot common issues.
Understanding RCBS Decapping Pin Sizing
RCBS, a renowned name in reloading equipment, offers a variety of decapping pins designed to accommodate different cartridge cases. These pins aren't universally sized; they vary depending on the specific caliber and case type. A poorly fitting pin can cause several problems:
- Damaged Cases: Too small a pin may not fully remove the primer, leaving it partially embedded. Too large a pin can damage the case mouth or even pierce the case body.
- Jamming: A loose-fitting pin may not consistently engage the primer, leading to jams in the decapping process.
- Inconsistent Primer Removal: An improperly sized pin can result in incomplete primer removal, leaving behind primer fragments.
Identifying the Correct RCBS Decapping Pin Size
RCBS decapping pins are often categorized by caliber. However, it's not always a simple one-to-one correspondence. Some calibers might share the same pin size, while others may require specific pins.
Where to find the information:
- RCBS Catalog or Website: The most reliable source is the official RCBS catalog or website. They will list the compatible decapping pin sizes for each of their reloading presses and the various calibers they support.
- Reloading Manuals: Consult reloading manuals specific to the cartridges you are reloading. These manuals often provide detailed information, including recommended decapping pin sizes.
- Online Forums and Communities: Experienced reloaders in online forums and communities are an excellent resource. Searching for your specific cartridge and press combination often yields helpful advice.
- RCBS Customer Service: If you're still unsure, contacting RCBS customer service directly can provide a definitive answer.
Important Note: Never rely solely on guesswork. Using the wrong decapping pin size can damage your equipment and potentially cause injury. Always verify the correct size before proceeding.
