Just looked - 19 different die sets in the drawer - each has a shell holder for my Rockchucker press and each has the Lee case trim pilot and its shell holder. Maybe made more sense when there was only three. Deciding to buy a new-to-me cartridge requires automatic inclusion of 200 new brass, FLS dies, shell holders and Lee trimmer set-up. I do keep just one of each needed size collet for the RCBS bullet puller, though. And haven't broke or bent a de-capping pin since I got the Universal de-primer (with spare pins for it!!)
