In a "subject" Model 700 .30-06 that I examined for an insurance company, the bolt's "solid ring of steel" around the head of the case broke around that much thinner ring of steel around the extractor. The steel there is just a bit thick for rolling a cigarette but rather thin for anything else (except maybe an X-Acto blade).<P>Debris flew and wild gas flowed. The shooter had a piece of metal removed from his eye. I didn't see it. The doctor had apparently discarded it. I didn't see any evidence of any obturation. Anywhere.<P>Another good theory blown to Hell.
