I've come into posession of a large quantity of WW2 and post WW2 50 BMG ammo and wanted to get a handle on pricing. Strangely, it seems silver tip API is actually cheapest, likely because many ranges don't like incendiary. Still, prices are all over the map for 50 BMG ammo. What is 50 BMG Black Tip AP going for per round these days? Silver tip API? Ball? I think my confusion comes from trying to gauge the different prices for reloaded and original milsurp AP/API/ball ammo. Why such the big variation? I'd assume that newly manufactured stuff would be more valuable, reliable, not less. What gives here? Thanks!
