[QUOTE="MagnumManiac, post: 2337574, member: 10755"] Working out actual case capacity in grains is really quite simple. Take a fired case of each, weigh them, fill with a 50/50 mix of water and isopropyl alcohol, fill to top of neck without the liquid bulging above the neck and weigh again. The difference is the capacity in grains of H2O. I do this on all of my brass, even on different lots. Many brands weigh similar, but their capacities are not similar because then webs and thick walls hold more and thick webs and thinner walls hold less. Cheers. [/QUOTE]
