This is hands down the worst attempt to "prove" anything...
You have edited in the bits that "prove" your theory, go make a video where you don't aim up slightly at the final few targets and edit in the times it hits whilst ignoring the rest for that as well, it will "prove" there is no bullet drop at all. I am sure if you tried long enough you could aim to the side of the targets completely and eventually find a few clips where they hit. Does that mean we should all aim to the side of our targets?
Any basic experiment requires you to show all the data not just the bits that support your point.
