IMO what you are seeing is a result of the grain direction of the paper target and NOT keyholing. Round nose bullets will produce torn edges at the bullet hole and the grain direction of the paper controls how that paper tears. If you want to see a clear demonstration of this then rotate the target paper by 90 degrees before shooting it. Had you used two different targets of the same paper and rotated one what you would have would be one target with oval holes in a vertical orientation and one target with oval holes in a horizontal orientation. It's the primary reason why the wad cutter bullet was designed because they produce very clean edged holes in a target.
