Rifled air pistols

Rifled

— boots that have on their inner surface the so-called rifling — grooves of a spiral shape, usually along the entire length. Due to the rifling, the bullet, when passing through the barrel, spins around the longitudinal axis; this makes it more stable in flight and improves its accuracy compared to a smooth barrel, especially at long ranges. On the other hand, with a short distance, the difference in accuracy is insignificant, and the rifled barrels themselves are designed mainly for bullets and are poorly suited for balls (although “omnivorous” rifled pistols are also produced). Yes, and rifled weapons cost, other things being equal, more expensive than smooth-bore ones.
