What's happening is that the Win. hull does not fall down FAR ENOUGH into the collet of the 9000. The oversize rim keeps it "UP" above the rim recess and the collet subsequently squishes the rim out of the case head. Try opening the collet adjustment nut a tad for more room, or simply push DOWN on the hull until it bottoms in the collet.
