Ended up taking it out today to see what would happen. Used the XD45 and XDm9c. Shot at 15 yards, 10, 7, then 5. Never felt anything come back at me but wore pants, kevlar sleeves, and eye pro, just in case. Looked like the majority of the lead landed immediately below or within the first 3' of the target.
You're fixin to get hurt, and I'm basing that off my own personal experiance, and that of some friends.
We used to shoot anything, including stuff like you have there. It was always just a matter of time before someone was flopping in the dirt bleeding like a stuck hog.
