RCBS MatchMaster Trimmer Collet #2 Features The RCBS MatchMaster Trimmer Collet #2 holds brass firmly in place within the MatchMaster Precision Case Trimmer keeping the case steady so each trim comes out precise and repeatable. Covering .350 .418 and .506 inch diameters this collet size matches cartridges including .30-30 Winchester and 7.5x55 Swiss among other similarly sized cases. A secure consistent grip on the case head is essential to accurate trimming and this collet is designed specifically to deliver that fit across its covered diameter range. Machined from stainless steel the collet resists wear from repeated clamping cycles during high volume reloading sessions. Because the MatchMaster system uses interchangeable collets reloaders can expand their caliber coverage simply by adding collets like this one rather than purchasing additional trimmers. This collet is intended specifically for the MatchMaster Precision Case Trimmer and is not compatible with other RCBS trimmer lines such as the Trim Pro series. Keeping a selection of collet sizes on hand lets a reloader move efficiently between different cartridges during a single case prep session. The RCBS MatchMaster Trimmer Collet #2 gives dedicated reloaders a dependable way to secure their .30-30 Winchester and similar diameter brass for consistent trimming.
