It's a little bit of a silly medium, but I hadn't seen many ballistics gel tests done with black powder and a ball and thought this may be interesting to some of you.
The Tl;Dr is that they're amazingly powerful within 100 yards or so and they fairly closely resemble the damage from a 1oz 12 gauge shotgun slug.
With a little understanding of the qualities of soft lead and the approximate velocities and weights, this shouldn't be terribly surprising, but it was still quite interesting to see.
