I have needed the exact dimensions of both the RCBS Rock Chucker Supreme Press and RCBS Partner Press a few times, as I was working on custom ways to mount them (like this portable reloading press stand). Unfortunately, RCBS doesn’t publish anything to help with that … so I made a template and thought I would share it in case it helps anyone else.
Download RCBS Press Mounting Template with Dimensions
The mounting template, contains the exact dimensions related to the mounting surface, but here are a few more dimensions for presses that are also helpful (and not published anywhere).
RCBS Rock Chucker Supreme (RC IV) Reloading Press Dimensions
- Mounting Surface Depth = 3 5/8″
- Mounting Surface Width = 4 1/2″
- Total Depth = 6 3/8″
- Total Width = 4 1/2″
- Width Between Mounting Bolts (Center to Center) = 3″
- Min clearance below mounted surface = 8 1/2″ (handle may extend below that further out, see photos below … I might allow at least 9″ to be safe)
RCBS Partner Reloading Press Dimensions
- Mounting Surface Depth = 3″
- Total Width = 2 5/8″
Update: I’ve provided full plans for building the portable reloading press stand shown above. Check them out at: Portable Reloading Press Plans.
I’ve been searching all day for this, thanks for posting.
Nice, I haven’t used my Rock Chucker in ages but need to remove primer pocket crimps on my LC 5.56 brass prior to loading on my Dillon and this is close to what I sketched out but yours mounting stand is much nicer. Thanks I will be “stealing” your idea.
I like the wood mount you did. Do you have more of a side picture? And a list of hardware used?
Hey Britten, I’m glad you asked. I actually posted a full set of detailed plans to build that portable reloading press stand, and didn’t realize that I never went back and added a link to it in this post. I certainly should have! It should definitely have everything you need to build one. I really have enjoyed that design. It seems ideal.
