I think it has been introduced with discussions of hydro-static shock. Somehow, it morphed to include the wound channel.

I think the idea is that hydro-static disruption occurs with handguns, too, but just not to the extent of increasing the permanent wound cavity. For that, the bullet needs to exceed about 2000 fps.
