Cause it generates lift.
Ballistic spindrift is when the spin imparted on the bullet causes a drift in the direction the TOP of the bullet is spinning in.
Bullets fired from a rifled firearm should NOT tumble in flight. If they do so, it is a sign of problems. This may be caused by different matters that all relate to the rifling in the firearm, and the bullet. First is rifling is badly worn, if the bore is oversized for the bullet, or if rifling is badly fouled with lead/ jacketing metal/powder deposits, the bullet will not be gripped by the rifling and spun, and may not be stable in flight (tumbling) Try cleaning the bore properly, and check for excessive wear at the muzzle. The second condition is the wrong weight/length of bullet for the rate of twist of the rifling. A fast rate of twist, combined with a very fast bullet, MAY result in the bullet "stripping", and not being spun by the rifling. Or a very heavy, slow bullet may not be spun fast enough to stabilize the bullet. Most .22 rimfire rifles are rifled to shoot 40 grain bullets accurately. If loaded with a 60 grain bullet, such as the Aguilla 60 gr SSS, the bullet will not be stabilized, and may tumble in flight.
The chances of spinning a three on a spinning disc depend on the number of possible outcomes. If the spinning disc has numbers ranging from 1 to 6, then the chances of spinning a three would be 1 out of 6, or approximately 16.7%.
bullet trains travel at 96.5 percent the speeed of a bullet No it doesn't. A bullet train does around 190mph normally and can reach 275mph. Depending on calibre, a rifle bullet travels at 1,500-2,000mph. So on average, a bullet train travelling at normal speed travels at between 9.5 and 12.6% of the speed of a rifle bullet.
Ginning is the process of removing the seeds from raw cotton, while spinning is the process of spinning the cotton into yarn.
If you assume both bullets are stable and flying point forward, the spinning bullet will have more drag; HOWEVER, the whole purpose of spinning the bullet is to keep it stable and point forward. If you do not do this, the bullet yaws and wobbles wildly drammatically increasing the drag. Therefore, in actual practice, the spinning bullet has less drag because it remains stable and point forward whereas the unspun bullet is unstable and wobbles/tumbles.
By spinning the wheel
The bullet is moving forward, and is spinning. As the bullet moves away from the gun, it falls towards the earth from gravity.
Ballistic spindrift is when the spin imparted on the bullet causes a drift in the direction the TOP of the bullet is spinning in.
Grooves in the barrel. That is called rifling.
Because a spinning bullet travels in a straighter line, for further, than a bullet which is not spinning. So, in a word, "accuracy" is why a gun puts a spin on a bullet. Not all of the guns put spin on the bullet though. Those that do have rifled barrels(grooved on inside). There are also smooth bore guns that do not cause the projectile to spin.
Spiral grooves are etched or cut into the inside of the barrel. These grooves are called rifling. As a lead bullet moves down the barrel, it heats and expands slightly. The edges of the bullet catch in the grooves and the bullet spins. The spinning motion helps the bullet to maintain a straighter course. A projectile that does not spin will begin to curve or tumble, wasting energy and moving off course. The spinning projectile keeps the nose end in front so that the bullet stays close to the target. You can actually see the effect of the spinning by firing tracer bullets at a target at least 100 yards away. The dye on the surface of the bullet leaves a visible spiral in the air which can be observed for a few moments if the light is right.
Striking it, igniting ythe charge (a little explosion) then spinning it.
The bore is rifled so as to put a spin on the bullet. This spinning gives a greater accuracy to the bullet, especially over that of a smooth bore.
Grooves cut into the inside of a gun barrel for the purpose of spinning the bullet when fired.
Rifling. The barrel is not smooth on the inside. There are small grooves spiraling down the barrel which makes the bullet spin. Nearly all shotguns do not have rifling in the barrel.
