OK so the next sentance he says "completely flat" - still...

I will agree that for all practical purposes, the two will hit the ground at the same time, even factoring in the curvature of the earth

Unless the centerline of the bore is pointed downward or upward, not parallel to the ground...

Umm...

After setting up your rifle so that the centerline of the bore is exactly 36" above and parallel to the ground...which happens to be completely flat.

If the ground is flat for at least 1500 feet in the direction you're firing, then the curvature of the earth doesn't matter. They will hit at exactly the same time.

question: is the rifle setup with a scope?

if yes, is the scope setup to hit a target and then how far is the target from the rifle?

also, how much is the scope base setup for MOA compensating, if any?

finally, what rifle is it?

Don't you mean Point Break? I think you're getting your 90s flicks w/ skydiving scenes all discombobulated, bruddah. Maybe you confused Terminal Velocity w/ Drop Zone. Gary Busey co-starred in the latter as well as Point Break.

Edit: Bah! ldivinag beat me to it, but Wesley Snipes was in Drop Zone, no?

Oh, and both bullets hit at the same time.

Now you set up the test rig which holds an unfired bullet exactly 36" above the ground and will drop said bullet when the fired bullet leaves the muzzle.

Which bullet hits the ground first?
I'd say this scenario is impossible, given the fact that Hornady doesn't make a .284/7mm V-Max bullet in 139gr.

i would think the horizontal movement of the fired bullet would create some lift on it, reducing Fg.
