I've done that with a muzzleloader and clay birds.
The club I used to shoot at had muzzleloader field competitions. They had a very nice walk-through course with reactive targets.
On field days, the last challenge was to split your roundball with the axe and break the clay birds.
It was TOUGH. IIRC, it was from about 15 yards.
