I found five 50-round boxes of "Hornady Custom Ammunition 5.45x39mm Russian 60 Grain V-Max Steel Case Box of 50" that I do not need (I don't have a gun in that caliber). This is listed online for $22.99/box and I'll sell it for $20/box. Or, I'll trade it for something I can use. . . make an offer. This is not a cowboy caliber, but I figure the sale or trade proceeds can be used to buy some cowboy friendly ammo.
