oh i'm going to mess things up. Any thing of similar shape will drop the same distance in a given amount of time, a feather and a rock don't apply as the feather has a wide enough surface (so would say a piece of paper) to trap air under so it floats down, if you sqeezed the feather into a ball then it would drop the same distance in a given amount of time. If you dropped a rock straight down, and fired a 300 win mag with the barrel level over a level area both would hit the ground at the same time. The test I did so many years ago when they taught us this silly idea in school was to drop a 1 lb and a 10 lb rock off a 30' silo. It still does't seem right but it is

What you don't mention, or maybe realize, is that if you were to take a bullet with a low BC (round nose) and a bullet with a high BC (Berger VLD) and fire them perfectly level with the ground at exactly the same velocity at exactly the same time the bullet with the higher BC will travel farther than the bullet with the lower BC because it is more aerodynamic and it retained its initial velocity over distance longer than the round nosed bullet did.
