I picked up a couple of boxes of XM162 today. They were in better shape than the one I already had, so I decided to open that one up. There was a box, as I fgured their would be, inside the vapor barrier wrapper. Inside the box, I found what look to be standard Winchester-Western Super X OOB. The date on the wrapper looks like JAN.-68. The rounds do look good in my Vietnam era pouch.
