I received a stack(Box) of 5 tins of JSB 18gn exact jumbo heavy pellets. On the top of the box was the LOT number and pellet size. This means there is no reason the seller can’t give you this information other then not taking the time if you ask for it.




Hi

The last two numbers at the top "20" is the year of manufacture(2020) and the bottom "0" is the identification number of the machine with which they were manufactured.

Yup, from the same tin no less. This was in October 2017. Weight was the same and shot just as good.



Mike,

Let me get this straight:

The four pellets in the magazine — the came from the same tin? 🤔 



If that is true (plz confirm or disconfirm) — I don't know what to believe anymore about what that manufacturer prints and glues on their tins....? 😟
