I am reloading 9mm rounds and as far as I know the right casefeed plunger is installed as I ordered the press setup in 9mm from Dillon.
If I tighten the shellplate to tightly the indexing ball bearing jams in the hole and the shellplate does not index correctly, I have stripped/greased and cleaned the press a dozen times and still end up with same result.
In response to Canuck's 223 response the toolhead does sort of realign the shellplate a little but nothing major as the toolhead has a bit of movement in in which I thought was normal I do not let the lever fly up or race the machine just slow and steady.
Just how tight should the shell plate be? should you need a little effort to move the shellpate or should it be a one thumb with no effort type push?
