Finally sprung for a Sinclair/Wilson Case Trimmer with the micrometer adjustment. In looking over what I load, and what I need for case holders and accessories- a few quetions have come up in trying to put together a list. Looks like trimming staight walled handgun cases will be slow at best with the standard handgun case holders - But wondered about the "Q style" holders for straight wall cases. Anyone have any experience with these or the standard ones? Also wondering about the Case Holders for "new brass". Most of my new brass is in .358 win and 45-70. Do I need the case holders for new brass? Any other accessories that anyone might recomend?
