In this article, I will explain the ballistic characteristics of Airsoft BBs.
The force acting on a Airsoft BB takes into account gravity, air resistance, Magnus force, and damping of hop rotation.
The diameter of the Airsoft BB is 5.95 mm, the temperature is 20 degrees, the humidity is 60%, 1 atm, and there is no wind. In addition, the change in initial velocity due to the resistance to withdrawal when the hop is strong or weak, and the Coriolis force due to the rotation of the earth are not taken into consideration.

The following is a trajectory graph with height on the vertical axis and distance on the horizontal axis.
The bullet is 0.2g, the power is 0.9J (initial speed is about 95m / s), it shoots horizontally from a height of 1m, and it is set to hop up to zero in at 40m. At this time, the muzzle hop rotation speed is about 208 rotations / second, the landing time up to 40m is 0.878 seconds, and the maximum lift value from the line of sight is about 25.3cm.
Furthermore, when it comes to 0.28 g Airsoft BBs, the trajectory is low, the maximum lift value at 40 m zero-in is 16.9 cm, the time to land 40 m is 0.838 seconds, and the bullet speed at landing is 31.3 m / s. The drop point will be 55m.

What we can see from these ballistic calculations and graphs is
1. The heavier the bullet, the lower the elongation.
2. The heavier the bullet, the longer the maximum range.
3. The heavier the bullet, the stronger the hop rotation required.

In this graph, horizontal shooting is the standard, and in that case, in the case of horizontal shooting from a height of 1 m and 40 m zero-in, the theoretical maximum reach is 55 m or less. You can extend the maximum range by increasing the hop rotation or shooting at an elevation angle, which will be described later.
Difference in trajectory due to bullet weight and power
According to the questionnaire, 54% of the respondents adjusted hops at 30m, which was the largest number.
The proper trajectory of variable hop-up depends on the distance to which the hop zeros in.
If you zero in at 30m, you need to shoot with a slight elevation angle to aim at a target at 40m. On the other hand, if you zero in 40m, you will hit the target with a trajectory that makes the bullet climb at 30m.
Also, when adjusting the hop, the height of the muzzle and the zero-in target must be the same to adjust correctly. If the zero-in adjustment is made to a target higher than the muzzle position, the hop adjustment will be weaker at the original distance.
After performing a hop zero-in, if you site in to that target, the bullet will fly correctly to the target location
A heavy bullet has a higher energy value when it lands, regardless of the distance to the target. Therefore, in Sabage, the penetrating power of the bush is high, and it is easy to make the enemy aware of the hit.
-The landing time is faster for light bullets at short distances, and heavy bullets overtake light bullets at a certain distance.
-Heavy bullets fly a little but far.
-Heavy bullets are more resistant to crosswinds.
For this reason, heavier bullets such as 0.25g and 0.28g are used in outdoor fields where long-range battles are likely to occur, and relatively light bullets such as 0.2g and 0.16g are used in CQB and indoor fields. It would be better to use them properly according to the situation.

Also, in general, lighter Airsoft BBs have a smaller bullet feed load than heavy bullets, and are suitable for use with high-cycle electric guns, and 0.2 g has the advantage that the unit price per shot is cheaper. Not all heavy ammunition has its merits.

Furthermore, it is better to use a weight suitable for the power of the airsoft gun to be used. A 10-prohibited air gun is 0.12g to 0.16g, a hand gun is 0.16g to 0.2g, and a long one is 0.2g to 0.28g. Of course, the conditions of use must meet the regulations of the field.
