You appear to be shedding primers during the ejection process. The primers in the lower box appear to be smaller. I see two very different primers, which might indicate one is factory and one is handholds. Is there any indication that the brass is soft, or the load is too hot (I do not see any such on any of the fired cases or the one fired primer)? The primers that are still in their cases, are they loose? Is there a flame cut circle on the bolt face, of the sort that comes from loose primer pockets before firing?
