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.

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.

the shortest distance between 2 points is a straight line but you'll find someone whos wants to curve it I guess.

The Nazis had a curved barrel that would allow them to shoot around corners, the pipe had a limited life and a port to release some of the gas but in the end the best way to shoot your target is to start by seeing it.

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*

Some of the level of myths are down right stupid now that it's pretty much all fan based. Like last weeks sonic boom one. The idea that a sonic boom can break a window isn't far fetched (The Thunderbirds flying faster than the speed of sound at 200 feet was pretty damn cool) But then they go on to say, some of the fans thought, any sonic boom will break any type of glass. That's when I go .

I knew they were going to go into firing a bullet next to glass and I already knew the results. That kind of crap makes it boring to watch.

Sure they are. If I have a bent barrel and I shoot around a wall, the bullet has curved in the course of traveling down that barrel. It comes out going straight but it didn't not go straight from the chamber (as that would drive the bullet out the barrel in a straight line) ergo it curved.

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.

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.
That's because it isn't spinning enough out of your launcher.

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.

Looks like bullets only curve up or down...


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.

The thread he's referring to changes the bullet design and spin to mimic a curveball thrown in baseball. The only differences between what is proposed and a curveball is the speed of the object and its density.

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).

That is talking about a traditional bullet. READ IT FIRST. The post in question is talking about a spherical bullet with side spin.

i remember one of their first episodes when they tested metal in a microwave. the dumb fucks used a microwave with a rotating glass dish, which greatly reduces the chance of the microwave exploding.

in most cases an older style microwave with metal in it will definitely cause serious damage. i have seen it more than once. first time was with a fork put directly on the floor of the microwave, second time was a hotdog pack with a wrap around label that was made of some kind of metal.
both practically exploded.

If you used a round ball, like from a musket, and were able to impart enough spin on it, could you get the bullet to follow a path similar to a pitcher in baseball throwing a curveball? You'd never be able to shoot straight with it, but would it not technically curve the bullet?
Link Posted: 6/17/2009 2:16:12 PM EST


They tested the myth because a number of people thought you could really do it. I had a few people here at USF that really thought you could curve a bullet like that.

I look at them like and asked them how did they get into here?

You idiots don't know shit.

Back when I was a Space Shuttle Door Gunner, we would use the Sun's gravity to curve 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.

Are you guys out of your mind? Of course bullets can curve. Imaginge a B-17 firing from its side gun at 90 degrees and moving at 250 mph. You'll see three forces acting on the bullet. The explosion in the shell, moving it 90 degrees to the plane, the motion of the plane, moving it forward (in the same direction as the plane), and third, gravity, pulling it down. Well if that bullet isnt curving, I dont know what is.

In that movie, they were "whipping" bullets around corners. Now that, can not be done. Were they trying to whip bullets around a corner?
