[QUOTE="entoptics, post: 1629793, member: 104268"] This seems overstated quite a bit, an example of the "appealing to the extreme" fallacy. If the cases were all run through the same sizing die (or fired in the same chamber), and are trimmed to nearly the same length, then the only dimension that could affect the volume/weight ratio is the the thickness of the case head or rim, since the outside dimensions are essentially identical. I can tell you for a fact that case weight is proportional to case volume in the above scenario. I weight sorted a huge wad of 223 brass at one point, and loaded an identical charge in the lightest and heaviest. The powder charge was visibly lower in the case in the lightest brass than the heaviest. [/QUOTE]
