RCBS Accessory Base Plate

It says the base plate will mount a Rock Chucker, case trimmer, etc. but does it mount the Pro 2000 press?

I would say yes from both of these picture from RCBS.

You could always just give them a call or e-mail. They are always more than willing to answer any question I have.

Edited to add: Just looked in their 2012 catalog and yes the 2000 will fit. See page 62.

Sweet - having both mounted to my little bench (plus the trimmer, plus my MEC 600 jr., etc.) makes it tough to maneuver. Thanks!

From experience, yes. Mine is set up like the top pic in post #2.

It will work. I use one with my Pro.
