I have 3 boxes of Western Cartridge Co., one of which the box is damaged. The other two, however, are nice with no tarnish. I have shot about 250 rounds of old 43' WCC ammo, and besides 20% of the cases splitting length wise, they all shot true. Fatigued brass is all I can think of. I'll probably sell or shoot the other 3 boxes, because I won't use them for HD.
