Buckshot,
I have been reading your posts on the machining you are doing. Looks like nice work. Also nice to know someone looks at their work and reflects on it before it goes out the door. Pride in workmanship went out with the quest for profit. You may not get rich but you will look at your work and at yourself and smile.
Anyway I thought you might be interested in Mecham Rifles push tru sizer die. If you haven't seen it here is a link.
