18 years ago I broke a Rock Chucker press casting with an 8x57 Lee collet neck die.
I adjusted it for 100 pounds of handle knob forcer as it went over top dead center [would be infinite force if not for friction].
RCBS sent me a whole new press, not just the part.

Now I adjust the Lee Collet Neck Die per the instructions.
