Abstract
Abstract A target for a rifle range has an upright with a rectangular opening adapted to be alternately occupied by two sheets carrying different target images. The sheets may be mounted back-to-back on a common support, such as a swingable frame, or may be interconnected to form an endless band led around rollers. The mounting frame can be internally equipped with electroacoustic or other sensors to serve as an impact-detecting chamber.
