Ditto what Kernal said.
I just backed the Lee sizer die off approx 1/2 turn after fire-forming and first reloading of .30/30 brass I reformed. (I used some Lee .285" 130gr cast bullets loaded to touch the grooves over 7.5gr of Unique- work splendidly, and was accurate, too).
Brass shows evidence of lasting forever......And accuracy is amazing from 21" bbl 5lb rifle.....
