Mr. Clark,
The History Channel's show "Battlefield Detectives" examined the battle of Gettysburg once and they looked at small arms fire and at least canister fire but I believe it looked at shell and solid shot too. It used plywood targets and not cadavers to examine the effects.
I hope this helps.
Respectfully,
