The 'news' program was saying that camming the bolt home causes the firing pin to set off the primer on some 700s. I bet that was caused by a dirty bolt face and/or sear and/or firing pin. But even so: why was the muzzle covering something (her son) the woman wasn't willing to destroy. Basic. Gun. Safety. Violation.
I figured it might a reload with a poorly seated primer. The lady probably didn’t know that slam fires occasionally happen when you close the bolt. Dirty rifle? Very possible.
And just why was she pointing the rifle at her kid? That is simply crazy, moonbat crazy.
