Well, thanks to reading a lot about .357 SIG and .40 S&W bulged out case issues, I headed out to add an RCBS Rock Chucker Supreme to the bench. Upon opening the box, I noticed that there aren't many parts included. Pretty basic design, so I wasn't expecting the setup to take very long. However, there were no mounting bolts/washers/nuts included! Off to the hardware store I go... Oh yeah, I plan on using the RC for sizing/decapping the brass I mentioned above. The Redding dual ring carbide pushy thing looks like it's the one that'll work with both calibers. I'll probably get the requisite powder measure, loading blocks, and hand priming unit just so I can also "drive a stick" in addition to driving the "automatic" 550.
