[QUOTE="Bart B, post: 560222, member: 5302"] And weighing cases is the most accurate way to determing case capacity. I've takes several primed new unfired cases of the same weight, and filled them with the same amount of water by weight. The water line came to different levels in the case neck. Proof to me that filling cases to the case mouth ain't a good way to measure case volume. The chamber's the same size for all cases fired. Cartridge brass is homogeneous enough that all cases with the same weight take up the same amount of space in the chamber. So when the case is fired and expands to fit the chamber completely, then and only then is its true capacity worthwhile. Weigh cases. Save water. Do it right. [/QUOTE]
