Was not able to find a Video ( with permission to use it ) like you wanted.
I did find a Hi-Res. jpeg. Bullet Image ( with permission to use it )

So Plan B. I made a " Burning Bullets " Dream with Fire rising from the bottom
and a waving motion for the bullets.
Should post today sometime , look for it , maybe you'll like it , I tried ...
