A few years back some of the better known revolver enthusiast (Hamilton Bowen, John Taffin, and a couple others) gathered at a friends ranch in TX.
They decided to compare the two rounds and see their effects on things shot by them. Deer, javelena, goats all shot with both rounds. The biggest difference between the rounds tested was the recoil. There was no noticeable difference in the wounds produced by each round and all animals dropped right there. The .41 did just as good a job on those light skinned animals as the .44 with considerably less recoil.
