I’ve got 5-6 sets of 310 dies, so I’m familiar with them, but I’ve never seen one like this before.
The sets got the decapper, neck sizer, neck expander, primer and seating die, so I’m guessing that this is an extra.
Just can’t figure out what it does.
Not long enough for a loaded round, so I guess it must have something to do with case prep.
