Hmmm So it indexes off the shoulder. The overall case length is not set, only the neck length. Is that correct? How does it keep from rubbing the shoulder? Or does it rub, but you can feel when it is done and stop before it rubs a thin spot?
It possibly sounds like I am criticizing, but I would love to be able to use something like this attached possibly to my 1/2 hp drill press, just press the case up into the trimmer. Then chuck the deburring tool and do that too.
Thanks for the info!
