What is the difference in these .25 Exact King Diablo's

Might be where they are made Czech Republic CZ 

Was the old numbering the die/lot number?? No clue, just a guess. I have about 20 tins of these, all say one or the other. I haven't kept them in 'purchase order'. It will take a while but I'll check results between tins. (Don't even have a .25 now but one is on order).

I just recieved 4 tins of the .25 cal

25.39 gr 2days ago from airgun depot and they are all the 72/09 marking.

intrested to see whats up with that myself,,,,

thanks

I just got 20 tins of the KH,s and all say M72/09. Also look on the back at an angle and you can see there's something under the label. The batch # and the factories label and bar code. So JSB's puts the big warning over the factories QC docs. I can see where the retailer would want to do that actually. 

I had a few tins where they were mixed. I posted it here about a year ago. Weighed the same and shot the same. 

i bought 8 tins from pyramid air both king heavy and MK2 25 cal pellets, both have the M 72/09 markings.

I bought 2 tins from Ebay and both say CZ. My pellets look like the ones on the left side of the magazine in the pic above..

The last two shipments of tins I received from Pyramyd were all labeled M72/09. Compared to the ones marked CZ, they shoot (in my Flex) a bit low, and a bit to the right. A couple of clicks, and I was back on target. The cause for the displacement could be anything.
