I know I'm a sign nut.

If the Rifle is perfectly level and the surface in front of rifle is perfectly level they will hit the ground simultaneously, if the projectile is dropped vertically at the same time as the projectile leaves the barrel gravity pulls them to earth at the same time, trajectory and elevation of a artillery piece was basic training for a Gunner in 1969

Actually, that would only be true if the earth was flat. the only way both bullets would hit the ground at the same time would be if the ground extended perfectly parallel to the angle of the shot, which would be perceived as the ground sloping upwards from the perspective of the shooter.
Otherwise, there would be an effective drop off of the level of the ground from the perspective of the fired bullet due to the curvature of the earth (however slight and imperceptible), which would remain in the air for a longer period of time compared to the dropped bullet.

That's what I said "if" the surface in front of the rifle is perfectly flat, to time the dropping of the projectile to the exact moment the other projectile left the barrel would involve more variables than the curvature of the earth most calculations use 8 inches per mile as a rough guide but it is slightly less

Your all wrong, you or your mate could easily catch the bullet falling off the table but I cant see even a 'bullet catching' illusionist catching the fired rifle bullet.

Thanks to the Navy Seals, OBL got to demonstrate the proper technique in catching a bullet.

Heh heh heh
You think the curvature of the irregular or even graded level earth over a 1000 or so yards makes a quantifiable difference?
I don't.

Remember the gun table is not tangent to the earth curvature, but rather a chord.
