"Points to pressure". Look at how the case head flowed into the extractor cutout. The other empties certainly won't look like that. Primer is deeply cratered where the metal flowed.

It looks (to me... I'm not an expert and don't play one on TV) like a serious loading error or one of those deals where the fire goes out just as the shot charge starts moving, and then reignites with the results seen.

No injuries we hope?
