RCBS.In my opinion, one of the top manufacturers of reloading equipment. Their latest single stage press the Rock Chucker supreme is a great design but have you heard where the frame which is cast iron is made? Thats right folks... CHINA! No joke, read this in an article in Shooting times a while back. The chinko castings are imported and the final assembly is made here. And this press is RCBS's high end unit! Don't get me wrong I own some RCBS components, mostly dies and have nothing but praise for them. But to import parts from chinkland really gripes my ***. Especially when msrp on this press is over $100.00. I'll bet Redding (numero uno IMO) still builds their stuff here. LEE Classic cast , Redding Boss and Big Boss, Lyman Crusher and CH4D are all AMERICAN made. Says so on the box.
