Firing a 338 Lapua with cleaning rod in the barrel

Scary stuff. Lucky he didn't get shrapnel to the face

When I was a kid, my dad's friend came over to shoot his muzzle loader. We were behind the house in the woods where my dad had a target set up. My dad had to go back up to the house to get something and I stayed there with his friend. Friend had already shot a few times. Friend loaded his gun and shot again. It was VERY loud and he was cursing because it had kicked so hard. He thought he'd accidentally put two loads of powder in it or something..... Until he tried to load the gun again and his ramrod was nowhere to be found. We never even found a piece of it.

I make the strongest possible recommendation against this practice.

Don't even do it with a bore snake - but definitely not with a cleaning rod.

OR ANYTHING IN THE BARREL...
