The RCBS MatchMaster Trimmer Collet #2 (RCBS part no. 9566) is a replacement collet sized for .418 to .506 diameter cartridge cases, built for use with the RCBS MatchMaster Precision Case Trimmer. This collet secures the case body during trimming so it stays centered and steady, delivering a precise, repeatable trim every time. RCBS designed the MatchMaster system with interchangeable collets so handloaders running multiple cartridge diameters can swap in the correct size without buying a whole new trimmer. Collet #2 rounds out that lineup for mid-to-large diameter cases that fall outside the smaller collet sizes.
