I'm sorry if this is already been covered here, and I am sure it probably has, but I could not find it via search. I got the Horandy Lock-N-Load conversion for my RCBS Rock Chucker Supreme press and I do like it a lot. So I figured I would post a couple of pictures. It's cheap, it's easy to install, and it makes changing dies a breeze. Definitely a thumbs up for this mod to your RCBS RC.
