Would be nice to know what the numbers do mean.

..................Still puzzled that different pellets come from the same die? Is the die set differently or line speed different. Would buy larger quantities but worried that the tins may have the same number but the pellets are different part way through a "batch".

Guess it is case of taking the risk.

Dean going off on a limb here but the die number is the tool number. That tool may be used for a great many number of batches before it is deemed to be worn out. Each batch may be a batch of lead/antimony alloy, smelted, then rolled or extruded to strip, then to be fed to the dies where pellets are stamped from the wire. As materials have tolerances each batch may be slightly different but falling within a manufacturing spec. This variability along with the variability in dies may lead to "good" batches and "bad" batches of the same product from the same manufacturer.
