The currently known mechanical slingshot shooting linear distance is not more than 30m. This distance is determined by the characteristics of the leather band, as long as it is still the power of the leather band, it will not exceed this straight-line distance.
As we all know, the process of slingshot shooting is also the process of parabolic firing. The farther away, the larger the parabola. The target of 20 meters does not need a parabola, and the direct straight-line distance is the so-called which to hit! Shooting distances of more than 30 meters all require parabolas, non-existence or straight-line distances. For example, a target of 50 meters can hit a target with a slight upward angle of the slingshot. 100 meters of target, shooting angle around 15-25 °.
After many actual measurements, the maximum range of the mechanical slingshot is far more than 200 meters, but the farthest can only hit the target within 200, which is limited by the sight. You can hit it, but you don't have to hit it. The maximum firing angle does not exceed 45 °, the parabolic stroke is too large, and the bottleneck has been reached. If you want to break through the ceiling, you must improve the performance of the leather band, or the field of view to solve.
