I just picked up a rifle. It started life as a 6.5 Jap. There was no ammo available after the war, so original owner converted it to 6.5x257 Roberts. He gave me a box of loaded ammo and a box of brass but he could not find his dies. Per the net, some call the round a 6.5 Spence. Any information or source of ammo would be appreciated. Thanks.
