Buddy of mine works with Powder River Cartridge Company. They mostly work with cowboy rounds, but he said they got a hold of some .223. Steel cased Wolf by the case, and some brass stuff by the box and partial case. Its higher than normal (I'm sure his price was too), but its there if anyone wants it.
