Since the current Obama regime and the DHS seem determined to buy up all the semi-auto pistol/rifle ammo that they can find(+22LR, .45LC, 30-30, 12 gauge #8 shot, .410 #9 shot, 7.69x39(?)), Tom Gresham's GunTalk talked about there being a possible new source of ammo from Australia in .223 and .308 calibers. I guess the company has been around a long time, makes ammo for the Australian military and makes all of it's own components(except the nonmilitary bullets--they use Sierra Gameking, Sierra MatchKing and Swift Scirroco bullets instead). You might want to give the website a look. I don't know who is the American distributor is or where you can get it. I think that Bell Extrusion Brass used to come Australia?
