one mile
as far as it wants
It depends on how high you are when you drop it.
Sorry, you need to specify WHICH .308 bullet and at what distance. As distance increases, the RATE of drop also increases.
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.
how far does a 50 caliber sniper rifle shoot accuratly
There isn't enough info to give a correct answer. What grain bullet? What type of bullet? What is the initial velocity? How high are your sights about the bore axis? What range is your far zero?
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).
ALL bullets fall at 32 ft per second per second. When you fire a gun, the bullet begins to drop as it leaves the barrel, To hit things further away, you aim higher. You can try this with a garden hose. Over a given distance, the bullet that will drop the least is the fastest- it simply gets there quicker, and has not had time to fall as far.

7400 meters.
about 36km
USABLE range is about 5900 feet. The bullet will travel nearly 5 miles, but not with usable accuracy.
