Default What are assault rifles zeroed in at?

Im having a hard time hitting prone and standing up enemies with assault rifles due to the bullet drop. I know sniper rifles are zeroed in at 600 something meters, but what range does bullet drop start to effect assault rifles?

assault rifles dont have bullet drop until 400m and markmen/sniperrifles are 600m

I was under the impression that the assault rifle bullet drop began at 150m, but it's 3:15am and I'm rather sleepy so it could be the insomniac fueled delusion talking here

1. Guns are not zeroed
2. Drop starts immediately
3. It is not noticeable for the first 2-3 hundred metres (vertical component velocity is small at this stage, this is compounded by the fact that the time of flight is only a small fraction of a second.)
4. tracers travel at 70% (? not a 100% sure of the fraction) velocity compared to non-tracer rounds :. Tracers will take longer to reach target and drop slightly more than non-tracer rounds.

Drop is very small in-game within the effective range of assault rifles, watch your tracers to give you a better idea of the trajectory of your round. keep in mind that tracers will have more drop due to their lower velocity and hence will impact lower (not by much though) than normal non-tracer rounds.

You are all wrong.

Assault rifles are zeroed at 300m. Sniper rifles are zeroed at 600m.

There are no proper ballistics. Bullets fly straight up until their zero mark, where they then begin to drop.

Savage, Exiled's got it right. in fact iirc it was Nedlands who was the first to explain the entire "concept" of zeroing at 300 meters. It's not so much that it's zeroed there as that the drop is so minute that the deviation has a far greater effect and so any drop is unnoticeable. The only feasible reason the Devs could have opted against using actual ballistics was that they prefered having realistic tracer:non-tracer ball ratios over realistic ballistics (see 4th point, explored by zangoo). I personally don't agree with that decision, but that hasn't changed much over each release so we can assume that there won't be any change any time soon.

It should be said that the only actual mod for BF2 with proper zeroing and range elevation was the Wookie Sniper mod (an awesome mod BTW). As I understand it, many of the people who worked on certain aspects of that mod are also within the PR community.

From what Jaymz has told me, the bullet flies a straight line up until the zero mark, from which there it begins to drop.

Perhaps it was not important enough to mention the minute drop the bullet undergoes up until the zero mark? Nonetheless, you do not need to worry about bullet drop until the bullet actually passes 300m.

As McLuv has stated, you should be more concerned about deviation.

although savage and exiled got two different explanations, they both mean the same thing (no/veryvery minute drop) up until 300m for ordinary rifles like the m16, but m4,tavor and other short barrel weapons have weapon drop after 150m as far as i remember.

Absolutely correct.

Jaymz was wrong.

I made the ballistics model to find exactly how a bullet moves in BF2, and it definately follows a ballistic trajectory. At no point does the bullet follow a straight line unless its fired either vertically upwards or downwards.

All guns in PR have traditionally been zeroed at 0m and the bullets have only a small amount of g affecting them.

Then if Jaymz's explanation is wrong, there still needs to be an reason why the sights/optics are pinpoint accurate up until 300m; not rising and then falling to meet their zeroed range. If this was the case, engaging targets with a sniper rifle at close range would require one to aim extremely low to compensate for the observed 'rising' of the round.
I think?
