Perhaps also with the many millions bring constantly produced the machines and dies have worn although I do know a large number of dies were replaced a few years back.
Not sure about the Lead quality Conor, the weight consistency has certainly got better though as even 2011 batches are vastly superior in weight to the die30's I use are crap which need weighing.
What I have noticed is the older pellets had a conical depression in the back of the skirt, these were swapped to a flat depression (as per Daystates) but I have a flat batch from 2011 that fly just as flat.....the latest ones seem to have a bigger flat that extends further back the pellet and these are the ones that drop lower at 45-55yds, maybe they are less balanced and more nose heavy
