Reloading your own ammunition can be a rewarding and cost-effective hobby, but having the right tools is crucial. One of the most essential components is the shell holder, and RCBS offers a wide variety of options. This guide will delve into the world of RCBS shell holders, specifically focusing on the size 3, and help you choose the perfect one for your reloading press.
Understanding RCBS Shell Holders and Sizing
RCBS shell holders are designed to securely grip and hold a fired cartridge case during the reloading process. They're critical for consistent and safe case resizing, priming, and powder charging. The number on the shell holder corresponds to the specific cartridge caliber it's designed for. RCBS shell holder #3 is a common size and accommodates a broad range of popular cartridges.
While size 3 might fit several cartridges, it’s crucial to check the RCBS compatibility chart or your reloading manual to ensure a precise fit for your specific ammunition. Using the wrong shell holder can lead to damage to your cases or even injury. Accuracy and safety should always be your top priorities when reloading.
Identifying Your Cartridge and Finding the Correct Shell Holder
Before purchasing an RCBS shell holder #3 (or any shell holder for that matter), you absolutely must know the exact cartridge you intend to reload. Different manufacturers might have slight variations in case dimensions even within the same caliber designation.
Here's a breakdown of how to ensure you're getting the correct shell holder:
-

-
Consult a Reloading Manual: Your reloading manual (e.g., from Hodgdon, Lee, or Sierra) will list the correct shell holder number for your specific cartridge.
-
Check the RCBS Website: The official RCBS website provides a comprehensive compatibility chart to match shell holders to various cartridges. This is a great resource for verifying your selection.

Double-Check: After purchasing, carefully examine the shell holder to ensure it firmly grips your cartridge case without excessive play or binding.
