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.
What is broaching a firearm?
A process of putting rifling in a barrel.
What is purpose of rifling in a firearm?
Rifling causes the bullet to spin through the barrel and downrange. This spin stabilizes the bullet, allowing it to maintain a straight course to the target. Without the spin, accuracy would be dismal.
What causes bullets to spin from firearm?
Spiral grooves cut into the inside of the barrel- known as rifling.
How do investigators match a bullet to a firearm?
The most commonly known method is by matching the markings left on the projectile by the rifling in the barrel to the barrel of the firearm. However, unlike the TV shows, where it's shown to be effective every single time, the actual success rate is in the vicinity of 68%, and even less so with firearms tested after a significant amount of time has passed since the test projectile was collected, as the characteristics of the firearm's rifling are altered during use by wear of the barrel

What are lands and grooves?
These are the 2 terms used in describing the rifling found inside the barrel of a firearm.The word lands refers to the raised portion of the rifling,and the grooves refers to the lower portion of the rifling.By applying a hole micrometer you may determine the caliber of your firearm by measuring the distance between the 2 lands,and measuring the distance between 2 grooves.if you then compare the measurements you will find the true caliber of your firearm.
What is a gun with grooved barrel called?
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
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.
Can you shoot the rifflins out of a 22 mag?
Not sure of what you are asking. If it is can you wear out the rifling in a .22 magnum firearm by shooting it- very unlikely. However, it IS possible to get a barrel so dirty that the rifling appears to "disappear", and accuracy is terrible. The cure is a thorough and proper cleaning of the bore with a good bore solvent, a bronze brush and rod, and patience.
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.
Why does your bullet tumble when it comes out of the barrel?
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.
