Do you have a source for this? I am not saying that isn't the case, but it would seemingly violate SAAMI standards and specifications.
No source, just going by what I heard on other gun forums {maybe this one as well?} including some where they opened up some rounds and mic'ed the pellets on camera. I'll see if I can dig anything up but its been a while.
Between the appearant size and construction variations {alloying, plating etc} I think its fair to say that specs for shotgun pellets are more like guidlelines than absolute rules.
