A Guide to Jsb pellet tin label meanings and what to look for

Look I'm a rank amateur, and I understand that most products have a batch number, but I just assumed that there would be some sort of effort to at least provide some sort of consistency in the overall product performance. The idea that I could buy a tin of JSB EXACT be really happy with them buy another and they will be useless doesn't instill confidence,
can someone tell me...

Does this same thing apply to all Pellets?

I am aware that manufacturers making ammunition for the military give every new run of bullets a limited colour code of a few hundred specifically aimed to be used by Snipers, which are measured and weighed to be identical for that particular batch.
 
Absolutely!

here is a quick explanation to hopefully help
:)

below the label reads 46560015 7 4.52
always work from the right on the main code
1. the last 2 numbers indicate the year in this case 15 indicating 2015
2. the 2 prior numbers indicate the quality control employee number 00 in this case
3. the 2 numbers before that is the production line employee number 56 in this case
4. the 2 before are the all important die number which on this tin is 46
please note you always work from the right cos if you get to step 4 and only 1 number then that's the die number IE dies 1-9
the 7 below would indicate the batch number
and then finally the 4.52 is the claimed size which is a load of rubbish.

in general the number that matters on JSB exacts it the Die number (please note there was some bad batches in 2015 on various dies)

I have just tried some Exact Diabilo in 4.51 and 4.53 in my Black Wolf and did not notice any difference. Should I now be going to Specsaver?

As I said a couple of years ago on this thread, the head size on JSB tins is just a made up number most of the time. Rarely do pellets vary that much and most when you measure them are more than 4.51, although I have noticed some batches are a bit bigger in the last year or so. In other words the size onthe tin is a guess. Ignore it, just go on a good die number that suits your gun. If you bought die 54 in 4.51 and die 54 in 4.53 I would bet that measured they are both the same size if from around the same date.
Start measuring them and you will get a shock!

Yes I said in my write up in the op it’s a load of rubbish
 
Has anyone had any luck with sizing dies? I've a bulk box of pellets that are tight in the magazine so I'm wondering if it's worth manually sizing them down or should I just take the loss and not use the rest of that supply?

I’ve used them before and quickly gave up as accuracy went out the window
 
Thanks for the info. Whenever anyone mentioned a die number. I was clueless. Now I can start looking and recording. Cheers
