A couple of related interesting websites. They have a good supply of fake bullets, blanks, dummy rounds, snap caps, movie props and more. For those who collect various cartridges they've got something interesting there as well for sale. They also rent out various props including military and farm animals. Is a bit off the wall in a way, but are great sites and likely thought inspiring and was just plain fun browsing around them.
