Got my 750 humming along. Still have occasional case feeder issue but nothing major. Will continue to adjust. Put Rubberband on bullet feeder die and it is dropping bullets . I have run some bullets and have discovered a difference between Missouri bullet co 230 LRN 45acp and my finally exhausted Friendswood bullet co 230 LRN(man they made a nice bullet...) the FW bullet let me seat at 1.27 oal but MBC won't chamber or drop test at that length. The shoulder on the MBC bullets are higher so to load them even with the lip of the brass I have to oal of 1.223. Not sure if loading to the shoulder on LRN is correct, but I remember reading that and it works. They now plunk test and chamber perfectly. Will have to live fire them tomorrow to see for sure.
