How many pounds should the 500 deflection be?

Deflection is actually a concept first put forward by foreign archery equipment manufacturers, and it is an index reflecting the toughness of arrows. Specifically, it refers to the hardness of the arrow, that is, the quantitative value of the deformation degree of the shaft after receiving the rated gravity within a certain length. The larger the value, the softer the shaft.

Simply put, the greater the number of pounds of the bow, the lower the deflection of the arrow, that is, the arrow should be hard. If the deflection of the arrow does not match the number of pounds of the bow, it will hit the arrow platform or the bow handle, which will greatly deviate the arrow, destroy the directivity of the arrow, and the accuracy cannot be guaranteed. In addition, the pressure on the shaft of a high-pound bow will cause great deformation of the soft arrow, and it is easy to hurt the arrow even if it does not explode, because the instantaneous force will make the deformation of the arrow exceed the safe range of the material.

As far as hunting is concerned, 600 deflection is suitable for a 40-pound bow, 550 deflection is suitable for a 45-pound bow, 500 deflection is suitable for a 50-pound bow, and so on. The number of pounds of the bow is inversely proportional to the deflection, which has a certain law, that is, for every 5 pounds of pounds, the deflection will decrease by 50, and the greater the deformation, the softer the shaft.
