JSB Pellets ?

JSB pellet tins used to have a "\\\CZ\" marking below the caliber designation, those were the older ones dating back more than 8 years, or so. The newer ones have a M46/08 designation, also just below the caliber type, at the very bottom of the label. Some tins are also labeled 26/23, probably designating the year when the design was changed... I don't really know.

I don't think your pellets are fake, but it is possible that there was a differently marked batch for export labeling purposes, or perhaps for changing the design of the pellet. JSB has a habit of changing stuff on their labels and the ammo itself. Me and a friend of mine still have a few tins of the older \\\CZ\ labeled .177 exacts (8.44gr) , because they just shot better than the new ones - those were the best .177 pellets I've ever shot out of my .177 guns and the two of us are saving them up for special occasions and long range shooting (cca.100 yds).
