Evilfish nailed it. There've been several experiments with bullet shaped or finned bbs, and none of them have gone far because a hop up system is so much more effective. While theoretically not as accurate at close ranges, a hop up system has a much further range/is more consistent at range.
The only practical application of these bbs in airsoft is for close range target competitions (like Japan hosts). With no hop up and a nice tightbore, .5" groupings at 10m (the typical range for these) would be possible.
