Bi-modal Distribution
This bimodal distribution certainly argues for two different swaging dies, or two different something at least. I'm wondering if the bullets were swaged from slugs of cut lead wire, and it was variation in the weight of the lead slug prior to going into the die that made the difference.
It might have been two different operators at the blank cutter, or (possibly) two different lots of lead wire (with one being just a hair thicker than the other).
Two different blanks, one 2 grains heavier than the other, might not be noticeably different to the swager operator.
