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.
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?
Not enough information to answer. What caliber? What type of bullet? What is the initial velocity? How high are your sights above the bore axis? At what range is your far zero?
That is going to vary based on what kind of "300" you are using, what the type and weight of the bullet is, what your initial velocity is, and at what distance you are sighted in for your far zero.
Depends on the range at which the rifle is zeroed.
1000 Meters = 1093.6133 Yards
as far as it wants
Depends on the velocity, shape of the bullet, and where the rifle is zeroed. For the standard .223 zeroed at 200 yards, bullet will be 1.4 inches HIGH at 100 yds, on target at 200, 7.2 inches LOW at 300, 22.3 inches LOW at 400, etc.
300 yards A pistol bullet can travel much further than 300 yards. On average, a pistol bullet can travel about a mile.
About 3,400 yards.
About 3,400 yards.
To the ground.
It depends on how high you are when you drop it.
