I don't beleive you can ship ammo via bus without violating the National Trasportation Act., Just spoke with my Canpar rep last week as we are a commercial soucrs for ammo and components, and they stopped since some went missing in transit and it became a criminal type security investigaiton, etc. safe storage of ammo???, so they can ship it, but they won't. DHL is about it, or a freight company. IT MUST BE IN Original Factory packaging or they can't take it either, as this is what was approved for transport, seperation is manditory for packaging, for approval so they don't bump each other.
Hope you follow, but I'm sure you are discouraged. Airlines allow a bit to be carried but you have to have original packaging and locked, and labeled, and quatities, are restricted, etc.
Not a simple thing anymore.
