Just got my 650 and it seems I have a problem. I am trying to screw in the Station 1 -sizing and depriming die. Instruction manual states to raise the platform and the bottom of the die should be about a "dimes thickness" from the shell plate. Problem is my die can only be screwed in so far and then it stops and won't go down any further. So my die ends up being about "4 dimes thickness" from the shell plate. Taking the tool head out and inspecting it from the bottom, it appears that that Station 1 of the tool head is made differently and, perhaps, this is what is causing my issue? You can see from the photo that there are two small indentations or "cuts" in the tool head on the bottom of station 1 that, I believe, is preventing the die from being screwed down farther into the tool head.
I did try sizing/depriming with the die set at this depth but only about 1/3 of the case is being inserted into the bottom of the die. This also prevents it from being deprimed. Any help would be appreciated.
