CCi VNT 17 Mach 2

Do you know what 17 Mach 2 is? Well, I didn't! "All ammunition sales are final," said the sales person. My 9-year old thought that was unusual and said as much but I assured him daddy knew what he was doing. Daddy did not however, know what he was doing and now these two boxes of 17 Mach 2 are sitting on my work bench just mocking me. One is sealed, the other is not. They're yours for $25 or best offer.
