Not exactly, while potentially colloquially misleading, in a legal sense it's perfectly acceptable, seeing as the oxford dictionary lists the definition as "An object which is forcibly propelled at a target, either by hand or from a mechanical weapon."
Cambridge has a similar definition, although they list "engine propelled" as the primary definition, with hand propelled as the formal definition.
