Long barreled gun, with grooves on the inside of barrel- is a rifle. Shorter version is a carbine. Handguns, such as pistols and revolvers also have grooved barrels.
A gun is a firearm whose barrel is not grooved (rifled), as with a shotgun, for instance. (A firearm whose barrel IS grooved is called a rifle. Examples include the common hunting rifle as well as the huge rifles on navy ships that can lob a shell as far as 25 miles. A firearm is composed of a barrel, a triggering mechanism, a chamber, and an explosive cartridge and bullet.
Grooves on inside of the barrel= a RIFLED firearm- the grooves are known as rifling. Grooves on the outside of the barrel= fluting, done to reduce weight
Terminology check: A musket is not a rifle at all - it is a smoothbore weapon. A rifle is so-called because it has a rifled (grooved) barrel. That said, until rifling came along, muskets were the shoulder weapon of most armies, yes (the purpose of rifling the barrel was to make the bullet "spin" - this greatly increased accuracy).
Grooves in the barrel. That is called rifling.
There are spiral grooves engraved on the inside of a rilfe or pistol barrel. When a bullet is fired, it is forced into those grooves, which impart a spin to the bullet. The grooves are called rifling.
Actually, the proper name is "cartridge." The term bullet is an extremly common but incorrect usage when referring to a cartridge. The term bullet only refers to the piece of lead that comes out of the barrel when the gun is fired. The bullet is one component of the cartridge.
The spiral grooves in a guns barrel are known as rifling. Its what puts a spin on the bullet as it leaves the barrel for accuracy. The grooves are called..... well, grooves. The ungrooved part between grooves is called a land. So looking through the barrel of a rifled firearm, you will see the "lands and grooves" that make up the rifling.

The size of a given bullet is determined by its diameter, and its weight. The size must match the size of the barrel it will be fired from, and heavier bullets will be longer. With cast lead bullets, after casting they are pushed through a machine called a die. This squeezes the bullet down to a precise diameter- this is called SIZING.
The barrel is straight. However, there are spiral grooves cut on the inside of the barrels. These spiral grooves, called rifling, make the bullet spin when it is fired. Just as a thrown football spins for an accurate throw, the spinning bullet makes for an accurate shot.
If you're referring to the metal tube the bullet comes out of, the very tip is called the muzzle. Behind that is the barrel. The wood/plastic piece below that, on rifles, is called the stock.
