For calling people a dumbass for believing that you can curve a bullet....



Seriously, how do these people function?



The Mythbusters tested the curving bullet myth from the movie Wanted and there are actually people that believe that it can be done.

IIRC the Germans had a device for curving bullets.

No, he's right. They experimented with an MP44 with a bent barrel to curve bullets around corners. I think the Russians did something similar as well.

This has zero to do with the topic at hand.

He recalled correctly.

There was a gun that had its barrel bent at about 90 degrees.  It didn't last long of course, but the gun did indeed shoot around corners.  The bullets always flew straight after leaving the barrel, dropping obviously for gravity, but it did work.  Then the barrel went *boom*

Quoted:


That is NOT curving a bullet. That is a curved barrel. The bullet still goes straight once it leaves the barrel.

The barrel was curved, the bullets still went relatively straight.

Yes, I KNOW. I've watched the Hitler channel before. The bullets aren't curving.

I suggest looking at the many videos of golf balls being used
as projectiles at YouTube. Also I have a golf ball launcher for my AR15
and it will send them 200 - 300 yards downrange and I've yet to see one
curve because there are no forces acting upon it to make it curve.

BTW, you are incorrect in your first post of that thread. Everything he originally posted is correct. The spin wouldn't be as much as in the movie, but it would be present. I suggest you educate yourself on the Magnus effect.

In external ballistics
The Magnus effect can also be found in advanced external ballistics. Firstly, a spinning bullet in flight is often subject to a crosswind, which can be simplified as blowing either from the left or the right. In addition to this, even in completely calm air a bullet experiences a small sideways wind component due to its yawing motion. This yawing motion along the bullet's flight path means that the nose of the bullet is pointing in a slightly different direction from the direction in which the bullet is traveling. In other words, the bullet is "skidding" sideways at any given moment, and thus it experiences a small sideways wind component in addition to any crosswind component. (yaw of repose)

The combined sideways wind component of these two effects causes a Magnus force to act on the bullet, which is perpendicular both to the direction the bullet is pointing and the combined sideways wind. In a very simple case where we ignore various complicating factors, the Magnus force from the crosswind would cause an upward or downward force to act on the spinning bullet (depending on the left or right wind and rotation), causing an observable deflection in the bullet's flight path up or down, thus changing the point of impact.

Overall, the effect of the Magnus force on a bullet's flight path itself is usually insignificant compared to other forces such as aerodynamic drag. However, it greatly affects the bullet's stability, which in turn effects the amount of drag, how the bullet behaves upon impact, and many other factors. The stability of the bullet is impacted because the Magnus effect acts on the bullet's center of pressure instead of its center of gravity. This means that it affects the yaw angle of the bullet: it tends to twist the bullet along its flight path, either towards the axis of flight (decreasing the yaw thus stabilizing the bullet) or away from the axis of flight (increasing the yaw thus destabilizing the bullet). The critical factor is the location of the center of pressure, which depends on the flowfield structure, which in turn depends mainly on the bullet's speed (supersonic or subsonic), but also the shape, air density and surface features. If the center of pressure is ahead of the center of gravity, the effect is destabilizing, if the center of pressure is behind the center of gravity, the effect is stabilizing.

Quoted:


A curve is, by definition, an acceleration (unless we're talking about a curved line on a paper.  I'm talking about an object traveling in a curved path).  For acceleration to occur, there must be a CONSTANT force acting on the object.  Adding ANY kind of force to the object at a single point in time can NEVER and will NEVER cause a curve - only an alteration to its straight-line path.  It MUST be a constant, steady force for there to be a curve.  When you flick your wrist when you fire a handgun, you're adding a force at one single moment in the bullet's travel.  That CANNOT, by the laws of physics, cause a curve.



Just give it to 'em scientifically and straight.  If they don't get it, f'em.

I was slightly disappointed to see that the team didn't try this in
order to replicate the myth, BUT, it is possible to curve a bullet, and
here's how:



Start with a smooth bore barrel, and machine a grove
in one side (left or right). Fire a lubricated ROUND (as in spherical,
not a 'round' as in a single cartridge) bullet (the shape is
important!) out of this barrel.



The bullet will curve because
the imbalance of pressure on one side of the bullet due to the grove in
the barrel will impart SIDE SPIN into the bullet, and the Magnus effect
will cause it to curve to the left or right, just like slice on a golf
ball or tennis ball, or a curveball like in baseball.



I'm sure
someone has already mentioned airsoft and how backspin is used to
flatten out the trajectory of the ball... in that case it's done with a
rubber strip on the top of the barrel, but if you fire the gun sideways
the bullet will curve (which is why you have to fire an airsoft gun
level if you want to hit anything).



Of course, you're probably
going to have to take into account that a since bullets are very small
and very heavy, and because using a grove isn't a very efficient way of
imparting spin, that it will take much longer than depicted in the
movie for the bullet to curve...and probably even further than a golf
ball takes to curve.



The good news is that you can track a
supersonic bullet (so keep velocity in mind) pretty easily due to the
shock wave being visible through a rifle scope (this is how snipers
keep track of their bullets).

Looks like bullets only curve up or down...

You idiots don't know shit.

Back when I was a Space Shuttle Door Gunner, we would use the Sun's gravity to cure bullets and take out targets that we couldn't even see.  It was tricky.  Too close and the bullet gets sucked in by gravity, too far away and it goes flying off into space.  Only SSDGs who were chief petty warrant sergeants and above, like myself, were allowed to do it.
