I even made a little graphic a while back because I was annoyed on this point.

Hi @Geez with recent changes to 1.12 there seems to have been a typo where 7.62x54 (Mosin, SVD) airFriction now has -0.0001, this was probably supposed to be -0.001.

Since recent changes to these numbers, there seems to be a typo in airFriction of 7.62x54mmR (Bullet_764x54). Too many zeroes.

This initSpeedMultiplier is also on the SKS, apparently. Real life, only 5% faster. In DayZ, 50% faster. Is this a typo maybe?

By contrast the initSpeedMultiplier on the Repeater rifle is reasonably correct. Winchester factory figures show a 1.48x increase firing the same .357 ammunition in a 4" revolver vs a 20" rifle.

@Geez I think the 18 points of damage for the .22 rounds is fine, because six body shots to kill player is reasonable for such a weak round. And it already kills player in one shot to head(brain).

That's interesting, and does this 320 km/h limit affect Expansion planes and helicopters as well? Hopefully this is a temporary measure until the underlying issue is fixed.

I did additional test and weapon with supposed 1700 rpm (reloadTime = 0.0353) fired at about ~890, the same as described above.

Buckshot and slugs don't have specific assigned colours, it depends entirely on the manufacturer. For example, standard Remington 12 gauge shells are green, and standard Winchester 12 gauge shells are red, whether they contain buckshot, birdshot, or slugs. You could even buy various 12 gauge shells and make a rainbow from the collection.

You forgot to account for deceleration of the bullet; something which DayZ simulates. In real life, muzzle velocity of the M4A1 with M855 ammunition is 2900 ft/s (884 m/s), but the bullet at the muzzle experiences a deceleration of 900 m/s², or 92 Gs.

As far as realism, ammunition is M80 ball, not the most accurate.

Is there a chance that we could see different types of .308 ammunition in the future? Maybe not just different types of .308 but variants of other types of ammo as well? That would be amazing and would add a lot of depth to the combat in DayZ.

The Winchester Model 70 has dispersion = 0.001 and the hunting scope adds -0.00025 for a final dispersion of 0.00075, or 2.6 MOA.
