Hemispherical bullets for airguns

Hemispherical

— bullets with a rounded, spherical head.

This form provides an excellent balance of performance and is considered the most versatile: it allows you to save both penetrating and stopping power, besides, it has a high ballistic coefficient. Because of this, it is hemispherical bullets that are most popular nowadays, and many long-range shooters consider them almost perfect for such tasks (although, of course, in fact it all depends on the quality of a particular brand of ammunition).

As for the overall shape, bullets of this type are most often made in the "diabolo" layout. Such an arrangement provides a narrowed middle part and a shank in the form of a characteristic extension - a “skirt”: when fired, such a skirt expands somewhat and is pressed tightly into the rifling of the barrel (recall, all bullets were originally created specifically for rifled pneumatics). This ensures stable spin-up and a smooth trajectory in further flight.
