Hello, im a viewer of the show. I recently seen the new movie Wanted. In the movie the main character learns to "curve a bullet". I was wondering if you would test this myth. I am shure that alot of people are wondering if this is true.

Complete rubbish I’m afraid.
A normal projectile is spun in order to achieve ballistic stability. This is imparted by the rifling in the barrel as the projectile travels along it.
To achieve a curved flight path like a footballer (soccer, player for you colonials) the projectile would have to be spherical and spun in a completely different direction.

Or someone could move faster then the bullet turn the gun just as the moment the end of the bullet leaves the barrel causing the bullet to cartwheel!

Dont think this would make it curve but! If it wasn't close to impossible it'd definetly be interesting

I think it worth of a try. I'd really love to watch them busting this myth. It might be possible to curveing a bullet. Although maybe they have to create a custom bullet (just like in the movie -jennifer lopez shooting a bullet with a "GOODBYE" on it..xP).


oftenly what you get is what you don't want to get.

It is expected by bullet experts that if you use a spherical bullet like those civil war type rifles use and use that on a gun with a barrel bent curve to an angle that the bullet would be spinning as it leaves the barrel. The spin could just be enough to cause a bullet to curve in the air. Of course there is also the magnetized bullet catch that they did in one episode which did not stop the bullet but it curved the path of the bullet towards the magnet and then there is also downward gravity as well that curves that path of the bullet towards the end of it travel. I hope they try and check the spherical bullet on a bent barrel.

I watched the program where they told how they made this film. It impossible to make this thing about bullet. And that gesture which he makes with the arm is used just because it's beautiful))

It won't work, even with a bent barrel. The plane of rotation required on a spherical projectile would prevent it form being fired from a barrel. In short, the rifling causes spin around the lateral plane (front to back)causing stability in flight. To curve it would have to have spin around the pitch plane (up and down).

Hope that's clear enough (pity I post diagrams).

ok ive been shooting and building guns for a long time and i would have to say this is somewhat real . but not at the extent the movie "wanted " makes it out to be . the reason i say it is real is anything kenetic remains moving unless out side forces interveen . so if you was swinging your arm say left real fast and you fired the gun as you was swinging the bullet would tend to sway left as it is moving though the air tward its target. one factor is :depending on the distance from you and the target it would be possable to get a noticable arcing of the bullet. it would take a high speed camrea to even tell the difference. as it would take a motorized shooting device to fire the gun as it is swung and a computer to get the readings from the device would be the only way to get true readings.
as i said the drift would only be a certin distance from the target. after that wind and rotational factors come into play that would stabilize the bullet to strait forward flight!
target aim to bullet hit will range different.it depends on the speed of the swing and the distance to target. my tests prooved a range or 1 inch to 15 feet in off center contact.
this was at the range of 50feet to 50yards. much greater effects could be at the 100yard range but i stoped my testing at 50yards. at 100 yards it only takes the bullet close to 1/6 of a sec to reach.thats moving 1100 fps.
after 100 yards the rotation on the bullet will take over and straiten the bullet out.
HOPE THIS HELPS!
AND IF ANYBODY WANTS TO TRY AND PROVE ME WRONG MY EMAIL IS : briphillipsonebay@yahoo.com
BUT JUST TO LET YOU KNOW I HAVE THE DATA TO BACK MY STORY UP! DO YOU ?
eq: a cnc motorized arm with a swing speed of 3500rpm.connected to a servo motor for the trigger pull. all of this is connected to a mechtronix cnc board (3 axis) 1. trigger 2.swing 3.height(aim) .
all this is tied into a program that i wrote just for the timing,firing,and aim of the gun.
i did this 3 years ago when i was setting up a remote firing range testing custom guns i build.

To swerve a bullet needs a constant force on it, not just a force as it travels down the barrel. Otherwise the moment it leaves the barrel it travels in a straight line ( well, except for gravity, which curves it down!).
To swerve it, you need to impart rotation to the bullet in the direction you want it to swerve. That uses the air to impart a constant force. Spin to the right, it would curve to the right and spin to the left it would curve to the left. The problem is that speed of rotation would have to be very, very high and it would only work if the bullet spins end over end.
It would probably be easier to make a special bullet that curved, fired from a smoothbore gun. The bullet would have a mark on it that indicated the direction of the curve. Each bullet would have to be manually loaded to set the curve! Because the gun is smoothbore, there would be no spin, so the bullet could be curved using a small fin. Because it doesn't spin, it would be hopelessly inaccurate though..!

ye i agree kevin u want summet its often what u dont get like when trying to target a footie to a target like bullseye aim its possible but solid very unlikly to pointpoint hit its annoying i no what you meen



oo and can sum1 tell me what this captain crew member thing is all about
