Yes it does. No adapter required. Easier to empty, reinstall and adjust. Accurate with the powders I'm using. I have a RCBS powder baffle in mine. The only downside is the non adjustable powder charge.
I use Lee Pro Auto disk with the regular Lee Powder Through Expanding Die (for pistol) on my Dillon 550 for 45 and 40SW. Easier to empty, install, adjust.
