I have fired an additional 75 rounds over the past two days with no malfunction. That first box that I went through must have been bad, it seemed every other round required a second strike, and the recoil seemed to be a bit more stout compared to Fiocchi. Must be because I brought my camera with me to photograph the primers.
I think most of my ammunition was made during 1955 and 1956. Might be a good idea to get these rounds into something more protective then their cardboard boxes.
