[QUOTE="Opa-lopa, post: 1651404, member: 108809"] 90+% of the volume/weight delta case/case within the same case lot is changes in the thickness of the case base, wall thickness differences account for the rest. My data says commercial production weight variation is about 1.6g for 30-06 case weighting about 200g, so less than 1%. If you put that tiny variance into Quickload or another interior Ballistics code, I think you’d be astonished how small an effect there is on MV. [/QUOTE]
