A new, crazy invention (by me)

Sorry if this should be in the lounge, feel free to move it there.

But anyways, I was thinking. Do you think it's possible to make a airsoft gun that shoots pellets, http://www.google.com/imgres?imgurl=http://www.gunmart.net/guns_for_sale/user_images/4896521.jpg&imgrefurl=http://www.gunmart.net/guns_for_sale/c/383/Pellets.html&usg=__llla_BaM9nxHlUMIz8xBoOMDcLk=&h=250&w=250&sz=9&hl=en&start=0&zoom=1&tbnid=bLAZf87l0ZprsM:&tbnh=123&tbnw=122&ei=yTCyTYL5O9PbiAL7nqGwBg&prev=/search%3Fq%3Drounded%2Btip%2Bpellet%2Bgun%26um%3D1%26hl%3Den%26sa%3DN%26biw%3D1281%26bih%3D680%26tbm%3Disch&um=1&itbs=1&iact=hc&vpx=130&vpy=84&dur=3672&hovh=200&hovw=200&tx=121&ty=103&page=1&ndsp=28&ved=1t:429,r:0,s:0 like those, but in plastic.
You could use a rifled barrel, like the tanikoba twist (not sure of the name, but something like that). The only problems I see is that could the spinning of the bb (pellet, really) wouldn't outrange the hop up on a normal airsoft gun, making this idea useless. However, the gyroscopic stability of the pellet seems like it would give you better wind resistance and accuracy, and combined with a pretty heavy pellet would make this gun very accurate.

Of course, this may be the stupidest idea ever seen, so feel free to tell me.
