Woops! Yes, you are absolutely right.

As for the blanks with plastic bullets. Yes they are more dangerous than standard crimped blanks, but for military training, I think they are the optimal solution. Proper cycling, and a nice big flame... its all there with much less recoil and no bullet holes I doubt they are used in movies much, if at all, but they are the only way that I can think of to have a live automatic firearm operate properly with blanks with no modifications.
