If the ram is a bit floppy theres ways to fix alignment issues .
Alignment issues apply to all sizers wether we hear of them or not !
I have 2 450s & I updated the handle toggle system & that took care of the newer 1 but the older 1 still has a little wobble .
I plan on D&Ting some brass screws to push the ram into alignment .
This is ok for older worn sizers ,but I would call Lyman & ask at least .
shippin costs ????
