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.
Inside the barrel.
Grooves cut into the inside of a gun barrel for the purpose of spinning the bullet when fired.
Essentially the same
because the rifling in the barrel makes it go straight.
The twist on the inside of a gun-barrel is called rifling. I dont know the specific pitch of the rifling in this particular gun but thought you would like to know the proper terminology.
Rifling a gun barrel causes the bullet to spin when it comes out. This makes the bullet fly more straight and greatly improves accuracy. Much like a spinning football spirals.
You compare the rifling marks on the bullet to the rifling in the barrel. You can also compare the firing pin mark on the primer to the firing pin on the gun.
broach is the tool to cut rifling.
It is a gun barrel where the rifling was produced by a method that did not force the inner layer of of the barrel beyond it's elastic limit.
a slug is normally use in a shot gun and they are not rifled a gun with a rifled barrel should shoot a Shell that is the same caliber as the gun.
It causes the bullet to spin which makes it go straighter.
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
