Abstract : An evaluation of four tracer rounds at subsonic Mach numbers has been conducted. This evaluation indicated that three of the four subsonic tracer rounds possessed large dispersion characteristics. The fourth round, the 7.62 mm NATO round, has acceptable dispersion characteristics; however, even this round demonstrated a dynamic instability at the subsonic Mach numbers. It was found that this instability can be characterized by a growing precessional vector and it is present with or without the tracer ignited. Data indicated that the instability is tolerable when the tracer is ignited because of its small effect on the dispersion of the round. (Author)
