weid wadcutter miniball

I was out digging around and found a weird wadcutter mini ball. It was fired out of a smoothbore as there are no rifling marks. it is roughly the right size for a bess(about.75 ca., its hard to measure as it is a bit beat up) It has a flat face and a true miniball cavity in the base. It also has three groves in the body. My question is .... Does anyone know what this is? I have no idea when it was fired.

could it be a fired shotgun slug? a few of the early shotgun slugs look "pretty old".

Is there evidence of the ogive & meplat being cut off?

Civil War soldiers were notorious for carving bullets to make chess pieces during down time...

You could have a .75 caliber rook...

Carved bullets from the Civil War...

Here is a Few Civil War slugs...

I'm thinking this is what the bullet was originaly, a .70 Caliber Austrian - MM313
