WOW!! How bad were you hurt?
Not that badly considering the damage to the rifle.
It shredded one arm pretty good with about a million pinholes filled with powder. Walking to the range office I left a blood trail that lasted until the next rain storm.
I also had a cut on my chest that wouldn’t heal so I finally broke down and went to a doctor. It turned out that a half inch long piece of the cartridge rim was embedded in my breastbone and was protruding outward so the skin wouldn’t heal.
The worst part was the flinching every time I prepared to fire a rifle. After all of these years I still have a bit of a problem shooting an unfamiliar weapon.
