[QUOTE="yorke-1, post: 1419469, member: 11960"] 80ml is a huge case, that's nearly 4.9 cubic inches! Capacity measurements I have right now are based on QuickDesign estimates which actually have the capacity at 102.7gr H20. This measurement comes from measuring the weight of a case filled with water to the case mouth. My case has a capacity that's about 20% more than a 270 Weatherby but about 8% less than a 270/300 RUM that I had before. I'm pretty conservative with my velocity estimates but some of that has to do with the relatively short 3.620" OAL that it's designed around. It's going to be a hunting rifle, so I wanted to design it around the Curtis Custom 3 round mag which has a pretty short internal length. I'm going to use one of the ARC Nucleus actions, whenever it shows up. I've actually used the 8x68s case before to form 375 Ruger brass and 338/375 Ruger brass to use in a Ruger 77 mk II. The design of the claw extractors gives enough grip on the case rim to extract the case with no issues, at least in my experience. [/QUOTE]
