I like the results I get from the LFCD so I use them. I know it's not necessary but it works for me. This post is about the (I guess?) new style unit. The older style dies had a body containing a free-floating ring to iron out the length of the cases and a screw-in upper part that set the actual crimp. The results looked good, IMO, and for $18+/- it wasn't a big deal. I had to get a replacement for the 9mm one I had (don't ask ) so I got a new one. This new one is a bit different. It's a one-piece body with no screw-in upper or floating ring. (I guess cost-cutting reasons) It looks like you screw it into the press until it hits the ram (same as older type). But the inside has no ring and you screw the entire body in or out to achieve the crimp instead of the moving upper part. Anybody seen or used one of these? I'd be curious to hear comments and will leave my own after trying it out.
