Another US 7,62 mm box found in Spain

Here is another 7,62 x 51 box found in Spain. I can’t date it because I didn’t keep any cartridges (or, worse still, I did some expensive plinking with them), but I don’t think it’s too old. There is a line in the part of the label covering the back of the box, saying: SMUFA Label 148, 14 Jun 65.

Maybe I have some of these rounds still, but they are undistinguishable from the normal ball loads.

¿Can anyone date this box approximately?


I would think that the label dates it more than approximately. Cartridges were most likely headstamped FA (+) 65 or FA (+) 66.
