I think that is the press I load on. It was my Dad's and there is another more current Turret press, but I never set it up, I just use the single stage Herters. I got shell holders off e-bay, they are out there for just about every cartridge. There is an RCBS adapter and I have one, but things seem to go better with the Herter's holders, the adapater changes the range of the ram to the die and I recall that creating some complications, so I just found Herter's shell holders. The primers fall down into the Ram in a catch and to let them fall out you lower the Ram the whole way down. I just hold a cottage cheese container or something like that and catch most of them, sometimes the primers get caught in the linkage and you have to sort of tap the handle/arm at the bottom a few times and the ones that get stuck or caught up usually fall out.
It is basic and not complicated. I kind of like the feel of it. The arm is kind of heavy, but there's way more leverage there than you'd ever need. I prime on press with it also. It isn't fast, but it seems to work pretty good for my uses. My Dad used it for rifle cartrdiges, and stuck with the Turret press for pistol. I just use the Herter's single for it all, but I'm not doing any bulk by any means.
