A supersonic bullet is a bullet that is faster than the speed of sound.
Yes, but it is travelling supersonic so you don't hear it until it has passed you or just reached you Not all bullets are supersonic.
The dry air speed of sound is about 1125 FPS, so anything over that is considered supersonic.
Some do, some don't. The bullet from a .45ACP is subsonic. There are a number of planes that fly at supersonic speeds.
.408 Supersonic Chey-Tac round. It uses a 419-grain or 305-grain cartridge, and uses a Spitzer bullet
One possible answer is, if the bullet is supersonic, the bullet will reach the animal before the sound of the shot does.
While in some cases the gasses are aided by the shape of the cartridge case, which becomes more narrow as you move towards the mouth of the case, the primary acceleration is due to the composition of modern smokeless gunpowder. Unlike the original black powder, which was a low explosive, modern powders are based on nitrogycerin and nitrocellulose. These explode with a speed that is above supersonic. Thus even a straight sided cartridge such as a .357 Magnum can drive a bullet at supersonic speeds.
movement faster than the speed of sound...:) precious A supersonic bullet is one thing that produces a sonic boom.
No, bullets are accelerated by rapidly expanding gasses. Those gasses are in a cylinder only open at one end. The bullet acts as a piston, and is pushed out of the open end of the cylinder. Not all bullets are supersonic, but those that are become supersonic from the amount of acceleration, and the time it is applied.
Some .40 caliber bullets are supersonic and some are not; it depends on the load. Generally lighter bullets (155 grain or less) will be supersonic, and heavier bullets (165 grain or more) will be subsonic, although there are a couple 165 grain bullets out there with advertised velocities about equal to the speed of sound. No matter what bullet you purchase, if you feel like subsonic/supersonic is a difference-maker to you, then check the manufacturer's specifications on the ammunition you're purchasing.

The supersonic man was very crazy.
