I have a bulk lot of Winchester .308 Win brass I bought around 2005 that ran from 152.5 to 159.5. Setting them out on paper in columns by weight revealed 4 different tooling sets were clearly involved in making them (4 bell curve peaks).
Were those sized and trimmed or at least trimmed when you weighed them or were they just pulled from the new to you box/bag ?

That brings up a good point for the OP . Were all those cases trimmed to the same length during case prep ? If not that can explain some of the variance .
