Weighed 5 mt unfired cases out of the bag. 113.6, 114.2,113.5,113.6,114.3 grains. Added spent primers to 2 for 117.4 and 117.1 grains. weighed 2 fired .223 cases. 1 LC and 1 hornady for 95.4 and 95.7. Both fired .223 water cap ended up at 30.9 grains water -- level full --. The 2 unfired .224 valk weighed 31.4 and 31.2 grains -- level full -- fired .204 ruger = 32.2 water level full. The valk cases weigh around 18 grains more than .223. I wonder how much h20 cap the fired .224 valk cases will gain.
This is a .223 and a .224 valkyrie with a 52 grain a-max at oal of 2.260. Think a .20 berger 55 might fit nice in a ar. Just spitballing.
