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 ass. 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.
