[QUOTE="BigNate, post: 2627760, member: 301"] It may be the brass has expanded just above the thickening portion nearing the case head. This looks to me like your first firing was way over pressure. How confident are you that you're not getting into the lands? Between your starting load and distance to lands you may be very near a failure. I'd recommend starting from scratch. Verify COAL with the brass and bullet you are using. Verify your starting load data, with consideration for primer variances as well. Starting lower may burn a little bit more in components, but will make finding an accuracy node, and watching for pressure signs easier than starting hot and trying to stumble across a good load. Are you able to chronograph your loads during development? [/QUOTE]
