Quote: I already make 256 Gibbs Magnum on cut down 6.5 Swede dies and 8x57 brass. So the above description (thank you!) isn't far off and the tools & assorted dies are already on the shelf,,somewhere!
BTW, a friend makes cases for his Mauser action .256 Gibbs MAGNUM by simply shortening the necks of 6.5x57 brass by 2 mm to 55 mm. He claims the .256 Gibbs Magnum is nothing else than a short necked 6.5x57.
