I have for sale 100 pieces of 30-338 brass. The brass is head stamped WW Super 338 Win Mag. I'm guessing the former owner formed 338 win mag to 30-338. The boxes were all marked 30-338, 1x fired and 2x fired. The necks measure out at 30 cal. $60.00 shipped. I can answer questions best I can and provide pictures if desired. Note I did not form this brass, I picked it up as part of a reloading lot that I picked up.
