We do not have a 204 Ruger case length gauge available. The case mouth diameter is too small for our Cutter to trim. Our Cutter can only trim cases that have a minimum case mouth diameter of .220" as our cutter has a .220 diameter hole in the center. This is where the gauge screws into the cutter for mounting. The gauge stops against the blades to set the depth. There is nothing there for a .204 diameter gauge to stop against.
We do have an alternative solution available to trim. The 204 Ruger Quick Trim die available in this cartridge to use in conjunction with our Value Quick Trim Case Trimmer or Deluxe Quick Trim Case Trimmer.
