does anyone know anything about this caliber? I've got some info from reloaders nest, but I'm reading all kinds of stuff with no real answers. I've seen several others asking questions too, with no answers. I can't seem to find anyone reloading this. I'm loading 223 and 45acp, so I thought I might be able to use 40 gr Hornady vmax, ex. for rifle and pistol if I decide to pick up a fn57. Any help is appreciated.
thanks
