yeah i had a look at all those youtube, one shot was okay but it was panning out the entire time. Shame i can't find that old footage. Wondering if any stock image places or something would sell such footage? damn this is tough!

It should be.  It's "bullets" for Christ's sake.

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 ) 

but not able to do the top to bottom flow you wanted.

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 ...
