Here is one account of a charging rhino shot by TR, but it wasn't at 10 yards.
The rhino dropped at 13 paces, and if the description is right, likely CNS crippled via the shot from the hunting partner. I like the second link better as it is a news account, but the same text.

Going back to Kreyzhorse's quote, Roosevelt referred to it as Ciceronian theory, basically that if you shoot enough, sooner or later you will hit. Today, we would call it spray and pray. Of course, Roosevelt, like the rhino he pursued, was poor of eyesight.
