步兵武器射弹散布有一定的范围性、对称性、不均匀性。然而这“三性”理论并非在任何条件下都成立。如果射击条件发生变化,则射弹散布规律必然也发生变化。步/机枪卧姿连发射击的射弹散布也是如此。在正常情况下,射手操作武器时,必然给武器的后坐过程中施加了上下左右诸方向的力,如果这些外力恰好确保 The spread of infantry weapons projectiles has some scope, symmetry and inhomogeneity. However, this “three-nature” theory does not hold under any conditions. If the shooting conditions change, then the rules of the projectile inevitably change. This is also true for the projectile rifle firing in step / machine gun prone position. Under normal circumstances, when a shooter operates a weapon, it is bound to exert a force in all directions up, down, left and right on the recoil of the weapon if these external forces happen to ensure
