[QUOTE="tobnpr, post: 2256297, member: 68758"] Machining defects in the chamber will show on your brass. "Mag length" doesn't mean anything- it's the boltface to datum line dimensions of your chamber, and the round that matter. Did you confirm your loaded round isn't being jammed into the rifling by using a comparator? Ditto on headspace- did you use a comparator to set minimal shoulder bump from your fired case dimensions? "Flattened" primers aren't always indicative of high pressure (pictures would help)- you didn't mention hard bolt lift when extracting the case, this is usually present with overpressure? Also, measurements of the fired cases compared to correctly sized brass. See if any are out of round, or otherwise out of spec. [/QUOTE]
