I made two different orders for some JSB .25 cal 25.39gr. After zeroing my scope and almost finishing one tin. I opened another can and dumped about 12 pellets into it. Started shooting the new can and my POI shifted down to the left about .75 inch at 30 yards. I than examined and measured the two pellets.
One had a thinker skirt and was .009" longer. The other one had a much noticeable thinner skirt and was shorter.
On my AT44 short the thicker skirt and longer pellet group better and more accurate by about 15%.
Things I notices on the labels:
Thinner skirt and shorter pellet. (The red label was faded and lighter in color).
Thicker skirt and .009" longer pellet. ( The red label is much darker in color and writing is more sharp.
This is consistence to the other 7 unopen cans that I have. Only two out of 8 cans had thinner skirt.
For 30 yards the grouping is very close. However if you if you don't want to adjust your scope inspect and match the pellets when opening a new tin.
