I will confess that I stole this from a guy on Youtube (NorthernInventor I think). At any rate it gave me an opportunity to practice on my new Sherline lathe. Some turning and facing work. Took a rod of tool steel and turned it down to fit loosely inside of 24 gauge shotshell brass. I turned the other side down to 1/4" to serve as a pilot for a 3/4" counterbore. When I chuck the counterbore and pilot into the lathe I just push the already shortened case onto the pilot until it stops. Perfect case length every time. Works like a charm. I feel quite accomplished.
