Mosin nagant Long Range, Magnus or Coriolis efect in game?

[kataro 59]

This is my question, mosin nagant in long distance shots, suffer physical effects, such as Coriolis effect or Magnus? That's because I noticed a slight change in trajectory to the left sometimes right.

The game actually models the entire solar system - no extra-solar planets, but obviously it includes the sun itself and the asteroid belt. Although the gravitational effects are slight they're measurable, and in fact several breakthroughs in the field of gravity wave physics have been made by studying the ArmA II engine. I suspect the planet Jupiter had aligned with the moon (e.g. the Earth's moon) and that's probably what's throwing off your aim.

I suspect they're not modelled because they're negligible in most cases

 

"At 1,000 yards the Coriolis deflection is small but not necessarily trivial. Una computed that at the latitude of Sacramento, a bullet traveling 1,000 yards would be deflected about three inches to the right. In addition, because gravity pulls the bullet down as it flies, you'd have to aim higher or lower depending on the degree to which you were facing east or west. If you were firing due east, you'd have to aim six inches lower, since the earth is rotating toward you, meaning your target would be slightly closer by the time the bullet arrived. If you were firing due west, you'd have to aim six inches higher."

"Overall, the effect of the Magnus force on a bullet's flight path itself is usually insignificant compared to other forces such as aerodynamic drag However, it greatly affects the bullet's stability, which in turn affects the amount of drag, how the bullet behaves upon impact, and many other factors. The stability of the bullet is affected because the Magnus effect acts on the bullet's centre of pressure instead of its centre of gravity. This means that it affects the yaw angle of the bullet: it tends to twist the bullet along its flight path, either towards the axis of flight (decreasing the yaw thus stabilizing the bullet) or away from the axis of flight (increasing the yaw thus destabilizing the bullet). The critical factor is the location of the centre of pressure, which depends on the flowfield structure, which in turn depends mainly on the bullet's speed (supersonic or subsonic), but also the shape, air density and surface features. If the centre of pressure is ahead of the centre of gravity, the effect is destabilizing; if the centre of pressure is behind the centre of gravity, the effect is stabilizing."

EDIT: More likely it's the natural scatter of the weapon (WW2 age etc) http://forums.dayzgame.com/index.php?/topic/160401-mosin-test-effect-of-bipod-video/

Long story short: Currently the mosin shoots slightly left of where you're aiming at longer distances. Bullet drop does work, zeroing doesn't as far as I tested about a week ago.
