most problems i had w/my 366 were w/the primer station.so i took the deprime off/the primer tube off/primer seater off and got a cheap mec to deprime/reprime hulls.when i reload w/the 366 all i do is feed hulls/ place wads and pull handle.works great.no primer half in and shot all over the floor,no fail to drop primer for what ever reason(failed to fill primer tray most of the time).works for me,but then i am the guy that drilled a hole in the top casting so i can change powder bushings w/out taking it apart.it works good also.to much time on my hands i guess. love this retirement.
