According to Federal, that load (the C44B) has a muzzle velocity of 1490 fps for 887 fpe out of a 4" barrel- it certainly doesn't lack in the "horse-power" department.

Looks like Dr. Roberts tested it here (there's a photo of the expanded round),

but I was unable to locate any further data like recovered weight, expanded diameter and penetration depth.

Perhaps Dr. Roberts could step in here with that data if he still has it?
