those civil war era muzzleloaders could put some serious velocity behind a piece of lead. i would say it easiliy could have gone straight through someone like that. (poor soul).
Nice plate. It does look like it was shot. Would have been a critical injury. Those bullets they used were deadly. Maybe the plate stopped the bullet some.
I think it had a broken hook on the back and they used it for target practice. They may have took bets on it. As far as I know it was only a camp site.
Looks like a bigger hole than a muskeball or minie, unless the bullet hit and jsut snapped it off, but that doesnt happen at high velocities...Looks the size of grapeshot, but since it wasnt a battle then it cant be that, maybe someone stabbed it with a pole or some tool? Or maybe multiple bullets were fired at one place? Or maybe if shot from long distance it would just snap a chunk off instead of going clean through.
It was rather common to use them as target practice when they broke as you said. Some of them that were used for bayonette practice as well. I have a plain-jane cartridge box plate that has about ten or twelve little triangle holes poked through it and a bunch of deep gouges where is was hit from an angle. First time I get back to Georgia, I'll snap some pics.
