I have 3 38 autos. I check the length for them only but do not trim. The autos get taper crimped. If a little long they go in the revolver pile. Some people with 52s trim the brass for better feeding. If you trim brass it needs to be trimmed AFTER it is resized for best results. The case mouth cracks are easier to detect. There are lots of answers at the bottom of this page.
