RCBS Matchmaster Trimmer .27 Caliber 3-Way Cutter Head

The RCBS Matchmaster Trimmer .27 Caliber 3-Way Cutter Head (RCBS part no. 90234) is a replacement or add-on cutter head for the RCBS Matchmaster case trimmer system, sized specifically for .27 Caliber caliber brass. RCBS engineered the Matchmaster line so a single trimmer body can handle multiple calibers just by swapping cutter heads, and this 3-way design trims the case to length, chamfers the mouth, and deburrs the edge in one motion rather than requiring separate tools. For handloaders working with .27 Caliber rifle brass, that combination cuts real time out of case prep while keeping every case mouth uniform for consistent bullet seating and neck tension.
