after a few mods my 1050 runs damn near perfect. first was the bearing plate, got ride of almost all the powder spillage. i run a bullet feeder on mine and used the m die to expand rather than the dillon, makes a world of difference seating 9mm 147 with the bullet feeder.
as mentioned in earlier post with primer shuttle and the rubber grommet thing, i bought the new primer shuttle. the big problem most people have is the primer tube nipple. they tend to get crushed or residue clogs them up. never tighten it down , just barely screw it on. use a new tip for the primer rod that goes inside. just buy a bag of those, they are cheap and a wear item. also make sure u do not have residue under the shuttle.
the case shuttle is also a area to keep lined and clean. i clean mine out after case prep since i notice more residue there after depriving. standard 9mm gets cleaned after 10k
also with the head adjusted on the press, do u notice any rubbing or resistance of the guide rods ? hat was my biggest issue, one was just rubbing and causing powder to go due to it hitting. i called filling they told me to see where it's hitting and use a small brass mallet to realign the guide rods from the tool head
after all those things, i have cranked out tens of thousands of rounds and who knows how much case prep, without issue.
only issue i have now is 1 out of 500 or so bullets dropping upside down in the bullet feeder.
im planning on automating this one with a mk7 and also buying another 1050 i like it so much. ps buy the time u buy a tool head and everything else, you are about $700-$800 in, so it might be better off buying a dedicated 650. i got 4 total tool heads and can swap calibers in less than 10 minutes taking my time.
