Bingo...ammo found

My understanding is that backspin creates lift via the Magnus effect, flattening the trajectory at the expense of velocity, but does nothing to stabilise the projectile in the same way rifling does.

It does improve things. Not as much as rifling, but it does mean each projectile has a predictable spin, rather than picking up a random one and just hooking off in any old direction.

The lower extremities being shown was intentional as hell. They will be fired when the design is done.....

Using your feet for ammo? Damn...that sounds painful!

well wouldn't it be almost as good as rifling? I figured since wouldn't it stabilizes the ball in both axis? The Backspin would stop it from developing side spin and it would also cancel out gravity for a limited amount of time if tuned correctly.

Does it?

All this talk about spinning makes me want to launch a baseball and try to tweak it so that it looks like a supernatural, wicked curve pitch or a sinker.

[mattyzip77]

That would be awesome!! Batter upppppppppppp! How would you tweak it to do that though??

[Gun Freak]

Put a hop-up-like device in the barrel at a certain angle.

[mattyzip77]

Thats what I was thinking, however wouldnt it just end up being backspin in the long run??

No, it will spin whatever way you out the hop up. In my airsoft gun, if I shoot it upside down, it dives. If I shoot sideways, it goes to the side.

Im pretty sure it would gyroscopically stabilize it

... in one plane, perhaps, but not along the direction of travel, which is the sort of spin that rifling provides...
