RCBS Trim Pro Case Trimmer Shellholder #38

The RCBS Trim Pro case trimmer holds brass in a numbered shellholder, and this is number 38. The holder catches the rim and keeps the case aligned with the cutter for the length of the cut.

A single numbered holder serves more than one cartridge, so confirm which ones fall under number 38 before ordering. Pull up the shellholder chart for your trimmer and match it against the brass you are trimming rather than ordering off the number by itself.
