M16A2 Shooting High?

[MAD MEN 1]

I found an M16A2 just recently and it seems to be shooting extremely high. I have found them before and never noticed it shooting like that. Anyone know whats going on?

Zeroing, Page up/ Down buttons. See if it fixes your issue with it.

Haven't had the M16 in a long time so I wouldn't know.

Weapons are generally zeroed to 300m in ArmA2. What ranges are you shooting at?

[MAD MEN 1]

Ok I'll try that thanks.

M16A2 is zeroed at 300 meters, you can't change it in DayZ.

Anything before that shoots high. Also I hear using SD ammo in it will change the zeroing to 1000 meters.

I was plucking zombies from maybe 250 and it was shooting maybe a 1/2in above the front sight. I know most are zeroed to 300m in arma 2, so I logged out and logged back in and it was shooting perfectly.... must have been bugged or something.

You're probably using SD ammo, and it appears to be a glitch; I'll try to explain.

Most assault rifles in Arma 2/DayZ are zeroed for 300 metres.

Silenced (SD) ammo has a much lower muzzle velocity than regular ammo, so it drops very quickly over range.

In order to make that bullet travel 300 metres, you need to compensate heavily for bullet drop. A rifleman in real-life would compensate for bullet drop by aiming above his target.

However, the game strangely compensates for this by literally changing the ballistics of the weapon, making the bullet arc upwards as soon as it exits the barrel.

Basically, if you use SD ammo in an un-silenced weapon, the ballistics seem to change significantly.

EDIT: I hope my shitty paint picture helps explain it a bit better than I could:

Oh ok yeah I was using SD ammo. But when I left and logged back in it was shooting fine?

If you had both SD ammo and regular ammo it would have loaded in the regular ammo on relog.

That could possibly be explained by how erratic reporting of the SD zeroing feature/bug is. A lot of people swear up and down that SD ammo zeros just fine, but a lot of people (including myself) have seen SD ammo shoot WAY high.

Might be a bug of some sort. Not the zeroing difference (as Nedarb explained, it's more of a feature than a bug), but instead the fact that sometimes SD ammo shoots like normal ammo.

I see, kind of annoying...
