I don't see how this would affect an individual who is not manufacturing smokeless propellant,and I can tell you from personal experience that guncotton is definitely a high explosive. At one time it was used as the bursting charge in some US shells, and I had to destroy one once. It was much more energetic than one loaded with TNT. Radford Army Ammunition Plant in Va manufactured Nitrocellulose for use in smokeless powder and had a good many instances where the Nitrocellulose line blew up.
