Yes, and no. There are three bits of actual important information on the back, the die, the year and the batch. Due to the way dies wear and are replaced, you ideally want to narrow it down to all three to guarantee the outcome.
First look at the tin you have, it'll have a number on the back of it, for example 3340020 then another sticker with 8 4.52 is on the tin in front of me. Read it from right to left as 20 being the year (2020), 00 being the QC checker, 34 being the production employee and 3 being the die, why do you read it backwards? Because dies can be single digit as in this example, and they don't use a preceding 0 to make that obvious. The sticker below with 8 on signifies the batch number and 4.52 is the claimed head size. With the exception of the calibre anything JSB claim about a tin of pellets contentments will be incorrect for the majority of pellets in that tin, eg the majority of 10.34gr 4.52 pellets have been neither of those things. Unfortunately, JSB's consistency just sucks, that's why people have tended to favour things like the H&N Baracuda 8's or QYS pellets now, they're generally more consistent. That said, for 50yds+ I still do better with older JSB Heavy stock I have.
