3-in-1 Case Mouth Cutter Trim Length

Q. I’m using the 223 3-in-1 Case Mouth Cutter on the Original Case Trimmer. Some of the cases are 20-30 thousandth’s over the trim length. I’m finding it makes the cutting much easier if there is a drop of light oil on the cutter head. Does this sound right?

A. Actually, we are surprised that .020” to .030” is being removed with the 3-in-1 as easily as it sounds. The tool is really designed to correct cases that have stretched from firing. This is usually just .003” to .006” of trimming.
