Apparatus for launching subcaliber projectiles at propellant operating pressures including the range of operating pressures that may be supplied by human breath

A combined blowgun and sabot projectile means, comprising:

• a blowgun, said blowgun including an elongate barrel provided with an elongate, substantially straight bore communicating between a breech opening and a muzzle opening;
• and
• a sabot projectile means, said sabot projectile means including a sabot projectile adapted for launch through and out said bore by thrust supplied by the breath of the user, said sabot projectile containing a sabot means and a subcaliber projectile means, said subcaliber projectile means containing a subcaliber projectile including a rearward-facing surface, and said sabot means containing a forward-facing surface adapted to abuttingly engage said rearward-facing surface in such a manner that said sabot means is configured to efficiently transmit thrust to said subcaliber projectile means during launch and separate from and discard from said subcaliber projectile means during flight after exiting said muzzle opening;
• wherein said rearward-facing surface includes a rearwardly opening projectile aperture, and wherein said forward-facing surface includes a forwardly extending, slender projectile engagement sabot protrusion, said projectile engagement sabot protrusion being adapted for insertion into said rearwardly opening projectile aperture, with said sabot protrusion being sufficiently narrower than the width of said projectile aperture such that said sabot protrusion is configured to be inserted into, and removed from, said projectile aperture, whereby said sabot protrusion and said projectile aperture are configured to engage in such a manner as to provide resistance to premature excessive lateral dislocation of said sabot means and said subcaliber projectile relative one another.
