Any other shaped bullet could cause feed jams based on the ammunition not being in the right orientation with respect to the chamber and barrel.
With cylindrical bullets, the orientation of the round doesn't matter.
A matter of practical convenience.
a bullet of the same caliber and same grains of powder fired from a long barrel will have a higher muzzle velocity than if fired from a short barrel.
No. People are not bullet proof.
Your momma is a cylindrical projection. oooh. burn.
Depends on the thickness of the platinum, the speed and weight of the bullet, and what the bullet is made of. A.50 caliber armor piercing bullet will shoot through some thicknesses of steel or concrete.

The momenta of the rifle and the bullet are equal and opposite. The bullet has greater kinetic energy than the rifle.
Rifle and bullet (The bullet is dependent on the rifle to accomplish its purpose)
The barrel guides and accelerates the bullet out of the rifle, and imparts spin to the bullet to stabilize the bullet in flight.
When a bullet is fired from a rifle, a chemical reaction in the gunpowder ignites, rapidly expanding gases build up pressure, and the bullet is propelled out of the barrel at high speed. The rifling in the barrel causes the bullet to spin, improving accuracy and stability. Gravity will eventually cause the bullet to drop due to gravity and air resistance.
There is no one answer- it depends on the rifle. They are generally less powerful than a full size battle rifle cartridge. The M16 rifle uses a 5.56mm bullet, the AK47 a 7.62mm bullet, etc.
That would depend on the caliber, and type of bullet, the rifle uses.
Have it examined by a good gunsmith. This rifle use a .22 caliber bullet, long rifle.
because the bullet and the rifle have equal and opposite direction,so a bullet have high kinetic energy and momentum
A cannelure is a ringlike groove, such as the fluting around the cylindrical part of a bullet.

Basically, a rifle is a place to direct the explosion of gunpowder directly to the bullet to increase the efficiency of gunpowder so the bullet can travel faster, and increase the bullet's momentum so it does more damage. The rifle also is used to increase the accuracy of the bullet. By focusing the blast directly behind the bullet, the bullet is more likely to travel in the intended direction. Striations in the rifle also spin the bullet so it corkscrews forward, making the path of the bullet straighter.
