the figure eight
The rear of the barrel of a revolver handgun, directly in front of the cylinder has a cone shape. That shape, known as a forcing cone, serves to guide a bullet into the barrel as it is fired.

The "crown" of any firearm is the front end of the barrel- the muzzle. It refers to a rounded shape of the end of the barrel.
No. The lead of the shot is MUCH softer than the steel of the barrel. However, if you have a RIFLED slug barrel, expect poor accuracy with any shot load- the rifling will make the plastic shot cup spin, and as it leaves the barrel, centrifugal force will make the shot pattern open into a "doughnut" shape.
Barrel racing is a rodeo event that involves you, your horse, and 3 barrels. It is a timed event. There are 3 barrels in the shape of a clover leaf. As you run in you go to the right side and turn the first barrel (but you can also go the other way and start at your left). Then you run to the second barrel and turn that then you are on your way to the 3rd and last barrel. as soon as you are done with that, you race home as fast as you and your horse can and to try and beat the clock. Barrel Racing is a very fun, but competitive sport. Some people think that to be a Barrel Racer you have to have an expensive horse but all you need is being able to enjoy such a fun and addicting sport!
Cutting an object with a pattern or shape to copy the same pattern or shape.
Bullets rotate due to the grooves that run down the inside of the barrel walls in a "helical" shape - this is known as "rifling". The grooves make contact with the bullet as it it fired down the barrel and cause it to spin. This improves its aerodynamic stability and accuracy.
Round shape

They are 'barrel-shaped' - in that they resemble a long, hollow cylinder.
The correct spelling really should be barrel-chested. Barrel refers to the shape, chested refers to the body region. A barrel-chested person usually has chronic obstructive pulmonary disease or COPD.
