So for many years I have had a RCBS Rock Chucker that was passed to me from a friend when I first started to load my own ammunition. It is one of the older ones. Only say "RC" on the side and has the older bicycle handle bar looking handle. Also it did not have a Bushing where the die threads through the press frame. Not could you switch which side the handle was on.
I have been looking for a new press lately and comparing a couple I found locally to my Rock Chucker. Today I picked up the newest variation of the Rock Chucker. Says Rock Chucker Supreme on the box and "RC IV" on the press frame.
I can say that this press is definitely larger. I noticed the height difference right away when pulling it out of the box. I also noticed that the ram seemed to be larger diameter. I measured with my caliper and the newer press has a 1" diameter ram. The older ram measures right between 7/8 and 15/16.
The ram on the newer press has a lot less play when at the top of the stroke. Presumably, because the older press has loaded tens of thousands of rounds.
Might be old news to some I guess, but I thought that I would share what I learned today. Overall this press seems to be well worth the $175 I paid at the local shop.
Now I wonder if the Hornady and Lee bushing systems will thread in the top if I were to remove the bushings. I would probably never do that, but I am betting they are the same threads.
