I’m for gun control, but it is important to realize that the wounds he describes could equally be made by a hunting rifle. The nature of terminal ballistics in this case is a function of the muzzle velocity of the round. This doctor is familiar it seems with handguns, which are generally no more than 1500fps. By contrast a hunting rifle will tend to be around 3000fps. For comparison, a shotgun shooting slugs with a heavy load might be 2200fps, but with more mass being moved. A .45 handgun will generally be less than 1000fps.
