Still working on one and will make a thread on it when I'm further along. Added a .080" strip to the bottom of an extra carrier in an attempt to get it to lift sooner. It worked, but it also tried to lift the carrier too high at the end of the lever stroke. So it need jigged up on the mill and the area around the bump thinned quite a bit. I think the front "U" section also need a piece silver soldered in to reduce the inside diameter so it can cut off anything at the rim diameter but allow the thinner case wall diameter through. Then a pin or block to limit how far back a case can go. In the end I may just end up milling a new carrier but I'd like to avoid that if possible.
As was asked please post a Link here to your new thread, so I get a notice
