making bulet go in a sircle (last shot of angalina)is imposible bicause of the phsicas involved but if you give it enough speed side ways you might hit a targaet bihind another target (what they traind on at first) but it will still go in a straight line

I think he's saying that a bullet won't curve as in the movie, but you can still somehow make the same shot with a straight trajectory.

Not quite sure how that's supposed to work, but in any event it has no relevance to the myth.

It should be possible to make a bullet curve -- for the same reason that it's possible to make a baseball curve. It's just a matter of giving it a lateral spin -- for example instead of rifling along the barrel, groves along one side of the barrel. It would be nice to see them make a proper effort to do this.

Comparing a bullet to a baseball is false science.. IT CANNOT BE DONE...

The reason a bullet spins is to stabilize its trajectory, not to make it curve in any way.. The reason a ball is imparted spin is to make it curve, due to the magnus effect..

Of course it can be done. The reason a bullet's spin doesn't make it curve is because it spins longitudinally. If it spun laterally, the spin would impart a curved trajectory, just like a baseball.

Of course, you would want to be using ball ammunition to do this, otherwise, you cannot impart a lateral spin in the barrel.

It still has nothing to do with what was shown in the movie, but Magnus does come into play to a very very small extent. An updraft or downdraft will cause a slight sideways curve, just like crosswinds deflect it either up or down through Magnus.

Right, it's impossible to make a bullet follow a curved path through any movement you impart to the gun itself. Only spinning of the bullet would do that (or wind or other external force).

I'd still really enjoy seeing them recreate the end result here. A bullet following a curved path through lateral spin (ball ammunition (preferably roughed up -- not too smooth) and groves down one side only of the barrel). This seems right down their alley.

As cool as the movie is, you can't do it with the gun. Once the bullet leaves the barrel, the gun no longer has the ability to change the path.

Old musket balls with no rifling will curve in flight, but their path is not predictable before hand. Other than that I know of no bullets that will curve around an obstacle.
