The not so good news on another Forum (ASSRA) that I frequent is that both Winchester and Remington have discontinued production of many cartridges except as loaded ammo.  These are mainly older rimmed cases including .30-40 Krag.  So there will be no more plastic bags of shiny new unfired empty brass.  This is more than a rumor.  Apparently Midway has confirmed.  Other calibers include the old WCF series; .25/20, .25/35, maybe .32 Special. Also .32/40 and maybe .38/55.

That means both your unfired brass and the OK fired empties just became a lot more valuable
