Jsb batches

[angrybear]

I try to get the same die Number each time. its the first 2 numbers on the red sticker on the bottom of the tin

I thought the first 2 were the machine press rather than the die ?

I know that's correct for the AA pellets made by JSB

The first number on the air arms pellets is the die number. This is probably the best to look out for rather than batch numbers.

No`s from left to right
Die No......39
Employee overseeing production... 00 (this seems to be unrecorded on all the tins I've seen, ie always = 00)
Quality Inspector........ 70
Year of manufacture... 12
BATCH..... 1
Head Size...... 4.53

Earlier tins may have a 7 digit number, like the yellow sticker above, they've dropped a leading 0, hence it's Die# 07 (Daystate Selects in this case, hence the S1).

Well, I've seen that original post/thread as well but it gives no machine press number and it's the press & die that matter.

I have an e-mail from AA telling me how to read the label on their tin (JSB made) which says press & die are all that matters, their first 2 are the press & best I can work out, by cross referring the tins, what you call the batch is actually the die number.

I'd also contradict the "always 00" bit because it isn't on any of my tins.

edit, I've just e-mailed them to ask.

If it's any help, our club imports about £300 to £400 worth of JSB pellets every month, and we haven't had any bad batches in terms of damage or poor manufacture for a year or so. Bear in mind though that some pellets are made with newer dies. For example, the Exact RS in 22 calibre is better made than the normal Exact Jumbo 15.9 grain, and it appears the 5.51 Jumbos are better than the 5.52 Jumbos. Everything in 177 appears to be well made. The 10.3 grain heavies are popular, another convert today.

Now that's what I needed to hear thank you rich as always a gentleman. I look forward to visiting your club again soon.

You are not making much sense Angrybear.I think what you maybe don't realise is that AA JSB's do not use the same numbers or configuration of numbers as on the JSB branded tins. Press and die is the same number really, ......on AA tins it is the first number before the date. Then the supposed size(which is usually wrong), then batch.

By the way it is now well proven that the sizes on JSB and AA tins mean absolutely nothing, so forget that bit. Also a die number with a different date is most likely not the same pellet as something will have changed.

Most JSB and AA pellets have been quite good over the last year or so in most guns that suit them, but they do vary from batch to batch. Die 8, 54,45 and 10 seem to have been quite good recently. Not too many bad ones though.

No, the press is the machine that the dies are fitted in to,
if the same set of dies is used in two different presses it's likely that different levels of wear & tear tolerance within the actual machine will produce slightly different finished pellets as a result.

The numbers may be in a different order but they will/should contain the same required information.
