A practiced hand with a single shot equipped with a ejector can probably keep up with the average goober with a bolt gun. Most shooters lower bolt actions at least part-way when racking the bolt.
I recently read about a PH school in Africa that keeps a Number One on hand for the students that fail the shooting test because they can't run a bolt rifle properly. The same students often pass with the single.
Phil Shoemaker, who knows a thing or two about stuff that bites (and shoots) back carries a nice customized Ruger quite a bit. He also has at least one double.
