That’s what I was thinking; she was using target practice bullets.
Not necessarily target rounds. Each shooting is unique. There are reports of criminals soaking up a dozen police 9mm hollow point rounds and still fighting. There are also documented cases of perps being shot in the head with a 45 Auto and still being a threat, as well as some taking at least one round of 12 ga 00 buck center of mass and still shooting back.
My home defense round is a 38sp wadcutter loaded to max 38 sp velocity. It will do the job.
This woman was trying to protect herself and her children, she did just fine, mission accomplished.
