Finished setting up my Dillon 750. I had originally ordered a standard height stand, but with the case feeder, it's too high for my ceiling clearance. So I replaced it with the flush mount from Inline Fabrication, which is perfect.
Installed a few Armanov accessories. I really like the powder measure quick release and the primer and case feed blockers. The only miss was the precision powder measure dial. I couldn't get it to work properly, and I ended up breaking the tiny internal gears, so I just took it off and went back to the simple bolt system.
I learned that it's really important to install the dies into the toolhead under load. I was having centering problems in station 1 with .38 spl when I just screwed in the die. Re-installing it under load fixed it. I'm having some snags with the case feeder, which were ameliorated by removing the plastic case deflector.
Setting up dies with a rotating shellholder is definitely a different experience than on a single stage press. I think the advice to start with a single stage is sound, as I was used to making the adjustments and was able to focus on controlling case feed/primer seating (either with the Armanov blockers or manually) and inserting and retrieving the partially assembled cartridges from various stations while adjusting individual dies.
I've got good loads for standard 9mm/115gn and .38 spl/148gn WC, which are what I shoot most, and I'm cranking them out in volume. I'm still figuring out a new load for 9mm/147 that will cycle my action while staying subsonic for a suppressor.
Do people find that the Dillon dies are better suited to the tool head than others? I'm using a mix of RCBS and Redding dies with Lee FCD. I find that some dies bottom out when properly adjusted to the point where there aren't enough exposed threads to engage the locking ring. Also, it's sometimes hard to access the rings for tightening. Watching youtube makes me think the Dillon dies are more streamlined and better suited.
