Expanding bullets for airguns

Expanding

— bullets with a head part with a notch (hollow point) or a cross-shaped notch (“dum-dum”). Due to this shape, when hit, the bullet seems to “unfold”, increasing in size. This greatly improves the stopping power, in this indicator, expansive ammunition has no equal. At the same time, for a high-quality deployment of a bullet, a high speed is needed upon impact (at least 200 m / s, and preferably 280 m / s or more); and the accuracy and range of fire with such ammunition is relatively low due to the resistance arising from the specific shape of the warhead. In light of all this, the main purpose of expansion bullets is to hunt small game at relatively short distances (ideally up to 20 m) using powerful rifles that provide high muzzle velocity.
