If the guy was wearing eye protection, he got off lucky, even if his handsome good looks are a bit impaired. I suspect he was sprayed by hot gas, and vaporized aluminum, lead, and jacketing. It looks like there's a piece of metal embedded in the scope lens, but it's hard to tell if any of the gas also blew back through the bolt body.
The rifle looks like a Savage 110. It's a tribute to modern design that the bolt held, otherwise he'd be on a slab in the morgue.
I use laser bore sighters and optical collimators, but on as a check on my work. Even then, I do a quick check of the bore when I button things up. I leave that stuff at home when I head to the range with live ammo.
Indeed , that individual better be in church this week at least !
Anybody that pays $1,200 for a Savage 110 deserves whatever happens to them.
