This is a shallow spiral groove cut into the inside of a gun's barrel. As a gun shoots, the projectile engages these grooves and they impart a longitudinal spin to the bullet. This creates gyroscopic stability which greatly increased the accuracy of the projectile.

How do they do the rifling in firearms?
Can be hammer forged, cut or drawn.
What is barrel twist?
In relation to firearms, it has to do with the rate of rifling in the barrel. Rifling is the spiral grooves that puts a spin on a bullet to increase it's accuracy. "Barrel twist" is the rate of spiraling or inches per turn. That is the length of barrel it takes to spin the bullet a full 360 degrees.
What is the name of a cannon or firearm with an unrifled barrel?
Smoothbore: muskets, musketoon, carbine, blundebuss, howitzer. Rifling made a great difference to accuracy of firearms. I would add to that Mortars.
What is the difference between micro groove rifling in old firearms and Ballard type in new guns?
the micro groove is button cut and ballard is the lands and grooves are not equally spaced
What is a rifle?
A rifle is a firearm with a shoulder-stock which is used to propel a bullet to strike a distant target. The Rifle is distinguished from the muskets of eras past, by the presence of 'rifling'. Rifling is the presence of spiral grooves cut into the interior of the barrel. Rifling induces a spin on the bullet resulting in more stable flight through the air. This spin has the effect of making the firearm more accurate by not only giving the bullet a straighter flight-path, but making the rifle's point of impact more consistent. (Consistency allows the user to properly adjust his sights to ensure his bullets hit where he or she aims.) Previous firearms such as muskets had no rifling. Today shotguns have shoulder stocks, but are typically smooth on the interior and have no rifling. (Some shotguns with rifled barrels exist to shoot specialty 'sabot' ammunition. While still called shotguns by the shooting community at large, the correct term for these firearms is Bore Rifle.) Modern handguns also incorporate rifling, but lack shoulder-stocks and are referred to as pistols.
Gun barrel rifling?
RIFLED firearms are those that have a method of making the bullet spin when fired. This makes for a much more accurate projectile. The oldest and most common means of doing this is buty cutting spiral grooves on the inside of the barrel. These grooves grip the bullet, causing it to spin as it passes up the barrel. The grooves are known as rifling.
Do wheel weights make good lead bullets for black powder guns?
Not really. Lead wheelweights can make decent bullets for modern day firearms. However, muzzle loading firearms have very shallow rifling, and need VERY soft lead bullets. Wheelweights are just too hard.
Why is rifling present in the bore of the barrel?
The rifling is there to spin the bullet, which gives greater accuracy.
What is a rifling number?
Can you be my girlfriend
Why is polygonal rifling faster than conventional rifling?
There is a lot less resistance with the polygonal rifling. More over, if the polygonal rifling is chrome lined, the walls of the barrel are completely slick and offer less resistance. The projectile, the bullet, goes way faster. IDPA estimation here in the US are 10-30% faster.
What is the original part of the bore left after rifling?
When rifled, the rifling tool cuts the GROOVES. Material left between the grooves is the LANDS.
What is rifling of the firearm. give purpose in a firearm?
The rifling in a firearm is designed to cause the project (bullet) to spin, increase stability and accuracy.
