It works for me. On the 650 you can put the lock ring on the bottom of the tool head or you can use the Lee lock ring turn it over and use the top side of the lock ring without the rubber ring. Or replace the Lee lock ring with the Dillon lock rings. You only need about ½ or more of one thread showing above the tool head for it too work.
