How hard would it be to form .358 Win. brass from.308 Win cases. The reason I ask is I can't find any 358 brass on the internet or anywhere else . I can't even find any cartridges(you know , ones already loaded ). It seems to me it shouldnt be a problem, but I know that Drop or Lever could give me the details on this one. The one thing about it is I can find the dies but not the brass. The sights the carry the brass are all out of stock.
