Several years ago RCBS obtained "O" frame castings from Red China, I have been informed. Presses manufactured from these castings were reputed to have numerous and severe problems, so severe that RCBS canceled whatever contract they had and reverted to American-manufactured castings.
I queried RCBS several years ago to ask how to identify Rockchuckers based on Red Chinese castings - to avoid them. RCBS would not furnish the information.
How does one identify such presses without buying a press and discovering its precision is poor?
