Thread: Playing with some Redding Competition Shell Holders

ok...so Im guessing these different shell holders work by shortening the distance the resizing die can possibly push down over case????
so the die firmly enguages the shell holder each and every time the same amount????
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???
