If you use oblong pellet the best way to stabilize (sp?) it's trajectory would be to use a rifled inner barrel, which will give a spin to the pellet, no need of hop up. If you don't use a rifled barrel nor a hop-up tje gun would shoot like a musket ie: anywhere but the targeted area. But here the pellet would need enough spin and enough velocity to keep a relatively straight trajectory.

As for the potential penetration ability I believe that is the ends are round enought the pellets woudn't have more penetration power than actual BBs. If the weight and velocity are equivalent I think that the effects on human bodies would remain equivalent. Of course if the pellets are sharp the will be more promt to cause bodily laceration.

It would be an interesting study to complete.
