Well we have the option of using 30-06 brass which is longer . The shoulder gets set back rather hard during resizing so annealing is a must. And the case must be trimmed downed down a lot to make AOL.
8X57 mauser can be used but the brass is more expensive. However the brass needs to be worked much less to be resized.
With that said i would like some input from you gentleman who have reloaded with either type brass.
