[QUOTE="Koda_, post: 3010656, member: 121268"] Production lots are the only way to track machining variations that I know of, but I dont think bullet manufacturers ship inventory by lot codes. We could in theory get a production lot of cnc turned bullets that weight .1gn different with even the best quality machining, add the rounding issue you mentioned it could even vary by .2gn. I have an order of Nosler partitions I weigh sorted, the spread was so bad I never used them. Weighing monos, I found Barnes vary worse than cnc turned bullets, not in an unusable sense (I like Barnes bullets) but I think the consistency of machined bullets aids in their accuracy so I switched brands. As I mentioned, I still mic bullet diameters only cause an out of spec bullet can cause pressure spike, again Barnes had the largest variation even in the same box. [/QUOTE]
