Gravity.
There is no one answer, since there is no one bullet. The drop of a bullet is a function of the speed- how long it took to get to 1000 yards. Some bullets will not TRAVEL 1000 yards. All other things being equal, the faster bullet will drop less.
yes
as far as it wants
Sorry, you need to specify WHICH .308 bullet and at what distance. As distance increases, the RATE of drop also increases.
The same as any metal.
not much
The speed at which a bullet drops due to gravity depends on multiple factors, including the caliber of the bullet, the initial velocity at which it was fired, and the angle at which it was shot. Generally, bullets drop at a rate of about 9.8 m/sĀ² due to gravity. Wind resistance can also influence the rate of drop.
Due to gravity, the bullet starts to drop the second it leaves the barrel. You can calculate the drop by factoring mass and velocity with gravity (9.8 m/s²).
To the ground.
No such caliber. Sorry. If you man the Lapua .338 Magnum, drop will depend on the ballistic coefficient of the bullet being used, it speed, etc.
No, this statement is not true. When a rifle is fired horizontally, the bullet immediately begins to drop due to gravity as soon as it leaves the barrel. The rate of drop will depend on the muzzle velocity of the bullet and the distance it has traveled.
