There was another member here who made a thread about how he was designing an airsoft sniper bullet like this, but in short it never materialized. I like your idea and I doubt many airsofters haven't gave it a thought, but I could foresee some legal and physics problems introduced. Any projectile with a length greater than it's diameter will tumble and change trajectory as it decelerates unless its axially spinning at a velocity proportionate for its mass to generate enough gyroscopic inertia to hold its path. Plastic is very light, respectively, and to get it to spin fast enough the barrel must be coarsely rifled and this creates great drag, which could be overcome with more pressure and airflow but this brings about some new problems. It would almost be easier to set it into spinning by using a high speed motorized wheel in the chamber and then fire it down a smooth bore barrel.
