and your shim rings sit in the gap somehow.....
to increase length of case...

so its like partial length resizing except its repeatable and very consistant????
the die is still the same but the amount it can push down over case is changed in controlled manner......
which also begs question,is a small base die...built shorter again so case body is pushed in more still???

The only small base die I have is for a 6mm BR and it just squeezes the area of the base in more. Shoulder bump remains the same. Have used a 308 small based die on loan and it did the same. Had a whole lot of once fired 308 brass given to me and no matter what I did it would not fit any of my 308 chambers. Had to borrow a mates SB die and once they were sized with that all was good for ever after. The chamber of the original rifle from they were fired in must have been huge.
