    Potassium nitrate is not impact sensitive nor is sulfur or charcoal.

    Because BP is made from base elements carbon, sulfur and potassium (with nitrogen) it will never deteriorate or breakdown. It maybe possible that the granulation size may be reduced down to dust by long periods of rough handling, but it would still burn with a whoosh or go bang in a firearm.
