The smaller the bow door (width) of the slingshot, is it more accurate?

No, the correct ball flying is thrown from the top of the bow eye, and there is no obvious difference in width, mostly 3.5-4 cm.

When the bow is in a stable state (that is, the slingshot is stable), a certain accuracy can be achieved within a certain distance of 25-30 meters through the contraction force of a pair of elastic bands with balanced tension.

In order to give full play to the role of the slingshot and hit the target at a longer distance, the front hand and the back hand must coordinate the forward and backward forces at the same time without changing the direction. The hand before holding the bow swings in an arc, and the tangent of the force coincides with the target direction pointed by the rubber band, which constitutes the "whip tip effect" mode.

The energy generated by the forearm swing, plus the energy released by the rubber band itself, will force the elbow force to reach the skin. When the rubber band is stretched to the limit, it will be sent out and whipped, giving the projectile more energy, making it fly farther and more stable, and achieving the possibility of hitting the target.

Extended data

Stretching rubber bands to the limit is not necessarily the best-each batch of rubber bands has the best service length, the best tension and stretching point, and not all of them have the best ultimate stretching effect. Only the best length, minimum trajectory radian.

The slingshot consists of a bow frame, two groups of symmetrical rubber bands and leather pockets with equal length tied to the bow fork. People hold a bow frame in one hand and a leather bag wrapped in a projectile in the other. The energy of the muscles that pull the bow is stored in the stretched rubber band. When the pinched leather bag is loosened, the stretched rubber band begins to shrink and release energy, and the stored energy is transferred to the projectile through the leather bag to eject the projectile.
