I haven't mastered pics yet, I'll try, but here is the url to egay listing the case slider on a Pro 1000 Progressive. It's for taller shells like the .223. I have looked all over elsewhere, Leeprecision.com, modwayusa, etc. No findy. I haven't done anything with egay for eons, and I'm sure my CC info is expired on payal, and payal is antigun anyway. Biggest malfunction is I can't figure out how to update it anyway, I'm puter challenged pretty bad.
