Incapacitating anti-personnel smallarms projectile

摘要

An incapacitating projectile to replace the conventional lethal bullet in the corresponding cartridges for various smallarms in general use, notably including police sidearms. In this projectile, propelled by a conventional smallarms powder charge, atmospheric air in a chamber inside the projectile -- as target impact retards the projectile body and a piston in this chamber travels forward -- is heated through compression, and further heated through friction, as the same piston travel ejects this intensely heated air upon its human or animal target, through a "pinhole" aperture in the projectile's nose.PP Because this arrangement incapacitates instantly by inflicting an intolerably acute localized burn, the projectile body may be of material of mass low enough to prevent or minimize the possibility of a serious penetrating or blunt-trauma wound. If the projectile body is of such low- mass material, the rapid decay of bullet energy downrange in the event of a miss obviates virtually all risk of its inflicting painful, much less lethal or serious, injury upon bystanders.
