How big is the slingshot? Are steel balls the best?

How many millimeters of steel balls are most suitable for slingshots?

I personally use 0.65 thick flat skin (taper: 20- 14) with 7.5-8 mm steel balls, and the trajectory is very stable; If equipped with 7 mm or less, the initial velocity is very fast, and the short-range power is also great, but the long-distance drift is a bit; There is basically no trajectory beyond 15 meters, and the accuracy is difficult to adjust, which is not suitable for long-distance shooting.

I have been playing 0.65 frameless since I was a beginner. The mainstream is 8 mm steel balls. Now it is not suitable to change other models of rubber bands and steel balls. After all, different rubber bands aim at different points. So I have been playing this mode; The delivery rate of this model 89 is also

How big a marble is suitable for making a flat rubber band depends on the tension and length of the flat rubber band. The tension of rubber bands with different thickness and width is different. The configuration of rubber bands and marbles is varied, so it is difficult to give examples, and it needs to be determined by calculation or experiment. I can only make a rough estimate here based on my own experience. I play slingshot, and the distance is about 120 cm. 2 kg steel ball with a tensile force of 6.5; 7~7.5 steel balls with 2.5kg pulling force; 3 kg steel ball with a tensile force of about 8; 9~ 10 steel ball 4 kg tensile force; 5 kg tensile force 10~ 1 1 steel ball; 6 kg tension hit 12 marble. My skin is usually flat, the maximum thickness is below 0.65, the tension is light, and the rebound speed is fast, which is suitable for 6-8 beads. If you want to increase the diameter of the steel ball, it is recommended to use a flat rubber band with a thickness of more than 0.7; Big saw, power is also a lever.

After all, different rubber bands aim at different points. So I have been playing this mode; The delivery rate of this 89 is still quite high.

Of course, the most important thing to play slingshot is accuracy; Practice more in peacetime. Finding the right action and aiming point is the most important thing. Don't blindly pursue strength, you have to fight 89, not wild boar. Too strong a rubber band is difficult to pull, your hands will shake and you can't aim accurately. No matter how powerful it is, it's useless.
