This is the dedicated .27 caliber cutter head built specifically for the RCBS MatchMaster Precision Case Trimmer. It arrives set up and ready for your .27 cal brass, pairing adjustable carbide blades with an included pilot so you can trim, chamfer, and deburr the case mouth in one clean operation. For anyone loading cartridges like 6.8 Western or other .277 bore rounds, having a head dialed in for that neck diameter takes the guesswork out of bench time.
The real draw here is efficiency. Because the head trims, chamfers, and deburrs in a single pass, you get a finished case mouth without reaching for three separate tools. The carbide blades hold their edge through long loading sessions, and the whole thing is machined from stainless steel for a long service life.
If you run more than one caliber through your MatchMaster, swapping pilots in and out mid-session gets old fast. Keeping a second cutter head already set for .27 cal means you skip the pilot removal and reseating step entirely. You pop the head off, drop this one in, and you are back to trimming. Reloaders who bounce between neck sizes in a single sitting know how much time that saves, and it keeps your chamfer and deburr settings locked in for that diameter.
The MatchMaster cutter heads, pilots, and collets are a newly designed, unique system. That means this .27 head is made to the same tight tolerances as the rest of the MatchMaster lineup, which is what keeps your trims consistent and repeatable. Worth knowing up front: this head is purpose-built for the MatchMaster trimmer and is not interchangeable with older RCBS gear like the Trim Pro series. If you are running the MatchMaster, this is the correct .27 caliber head for the job.
Yes. Part number 90234 ships as an assembled head with a .27 caliber pilot already installed, so it is ready to use out of the package. You can pull it out of the box and get straight to trimming .277 bore brass.
No. The MatchMaster cutter heads, pilots, and collets are a newly designed, unique system built specifically for the MatchMaster Precision Case Trimmer. Older RCBS accessories from the Trim Pro series are not compatible with the MatchMaster, and this head is not compatible with those trimmers.
The MatchMaster kit ships with one cutter head and seven pilots that you swap in and out. Keeping a dedicated .27 head means you skip the pilot removal and reseating step during caliber changeovers, which saves real time if you load multiple calibers in one session.
The carbide blades trim the case to length, chamfer the inside of the mouth, and deburr the outside all in a single operation. That means you get a finished case mouth without switching between separate tools or steps.
