“Camming Over” to Bump Case Shoulders during Full Length Sizing

Q. The Co-Ax® Press instructions say to adjust the FL Die down to touch shell holder. Other manufacturers say adjust down to touch shell holder, then go another partial turn. Then the press “cams over”, even without a shell. I’m having issues with tight bolt lift on 243 WSSM. Lowering the die helps some, but I am concerned about excessive wear on the shell holder. Is your shell holder assembly strong enough to handle lowering the die till it ‘cams over’?

A. Yes, it is strong enough. Our shell holder system is certainly designed to accommodate the “camming over” of the die against it. Many times it may be necessary to pre-stress the sizing setup to adequately “set back” the shoulder of fired rifle cases.
