Как меняется дальность стрельбы от скорости вылета шара. Выхлоп 100 - 140м/с в страйкболе.

This test doesn't claim to be the most accurate. At a minimum, the test would ideally be conducted with different paintballs, with tracers (so the flight itself is visible), with two cameras, etc. But in that case, the video would be an hour long.
