Is Bullet Drop IRL?

No, the real bullets empower themselves with the air resistance; thus remain in the trajectory solidly until a target is hit.
Although, when a bullet reaches its maximum distance, Chuck Norris will roundhouse kick it to get it going again.

That apple hit Newton hard. There is no gravity, nor does anything but pure magic affect bullets.

bullets don't drop in real life.
If you shoot in real life the bullet goes straight untill it leaves the planet and shoots out to space.

The maps would have to be huge for it to be a major factor, which negates the point of having the ballistic physics in the first place.

In 10 seconds a bullet would drop 490m. This can be figured by using the formula d = 1/2gt^2.
In BF3 objects fall at a constant velocity with no acceleration, so no, its not realistic.

Serious answer is

.308 =m40a1 ect 165 gr., .447 B.C.
Range (yards) Muzzle 100 200 300 400 500 600 700 800 900 1000
Velocity (fps) 3000 2788 2586 2393 2208 2031 1863 1704 1557 1422 1302
Energy (ft.-lb.) 3297 2848 2450 2097 1785 1511 1271 1064 888 741 621
Trajectory (200 yd. zero)-1.5 1.5 0.0 -6.7 -19.4 -39.3 -67.6 -106.1 -156.5 -221.4 -303.6
Come Up in MOA -1.5 -1.4 0.0 2.1 4.6 7.5 10.8 14.5 18.7 23.5 29.0

so your looking at 30 inches of drop with a fairly hot loaded 3000 muzzle FPS load

thats with a Zero @ 200 yards

If you accurately measured and implemented everything to do with bullets into a game like BF3, where the maps don't have terribly long ranges to shoot, you would end up with a canned system where the weapons may as well be hit-scan at all but the most extreme of ranges.

http://en.wikipedia.org/wiki/Barrett_M98B [en.wikipedia.org]

Projectiles in BF3 have a constant velocity, if the projectiles were mostly accurate you would have the M98B with 1.4x the velocity of BF3 and practically no drop over the standard range of ~500m. People would cry OP as most people couldn't handle "reality" in a game.

All right, here is basic ballistic trajectory (high school physics), it does not include air resistance or any other air effects. Also keep in mind that acceleration due to gravity is independent of mass (so in a vacuum, a feather would fall at the exact same rate as a brick).

Displacement in the X direction = cos(angle to the ground) * muzzle velocity * time

Displacement in the Y direction = 1/2 * -9.81 m/s^2 * time^2 + sin(angle to the ground) * time


They are really simple formulas so they could easily be implemented into the game. Leaving the only reason they don't use them is because of balance/gameplay choice.

Probably, the closest thing to your idea would be found in the ArmA series, the video below illustrates what I mean:

BF3 greatly exaggerates bullet drop. Projectiles moving that fast go much farther. I can't speak for Arma as I've never played it, but I did play Red Orchestra 1 & 2 and in those games the bullet drop was realistic - they dropped off, but not as dramatically.

Also worth noting you had to dial in your rifle sights on RO.
All problems can be solved with an appropriate amount of high explosives and duct tape.

Does a sniper shot IRL drop 30 meters over 10 seconds?
Like in BF3
Yes its called Gravity.

You do realise how much of a pain in the arse that would be right? At the moment bullets in BF3 travel in perfectly straight lines (symthic), just with an angle of projection below the horizontal. I.e. Rounds have a constant downward velocity.

This means they don't have to calculate parabolic trajectories for every single round being fired in the game every second. So it's a pretty decent optimisation and one that few people notice. At the moment only sniper rifles have different drop rates to the other guns.

So no, the bullet drop in BF3 is not like what it is in real life. However it's a pretty decent model of it for the purposes of the every day gamer. Maybe in a few years when the average PC and server are even faster and beefier, then we might get more detailed ballistics.

Gravity isn't real in real life because you can't explain it.

Cause think about it; sometimes you think that maybe it is there by now we know that it may be this that it will sometimes conclude by doing that to it

Like in BF3

Usually you count bullet drop in inch/cm at X distance...
