Why is a rifle barrel rifled ‘?

rifle, firearm with a rifled bore—i.e., having shallow spiral grooves cut inside the barrel to impart a spin to the projectile, thus stabilizing it in flight. A rifled barrel imparts much greater accuracy to a projectile, as compared with a smoothbore barrel.

What are the spiral grooves inside a gun’s barrel?

Rifling refers to the spiral grooves that are cut into the internal surface of a gun barrel. Rifling helps impart a spinning motion to a bullet when it’s fired. A spinning bullet is much more stable in its trajectory, and is therefore more accurate than a bullet that doesn’t spin.

Why does a spinning bullet fly straight?

So, when the bullet has some spin, it has some angular momentum in the direction of its motion. This spinning adds stability, because the bullet itself doesn’t want to turn on some other axis, thus changing the direction of its angular momentum, so it stays pointing straight.

How long does a rifle barrel last?

A barrel’s life expectancy is caliber dependant, and may range anywhere from 1000 rounds to 6000 rounds or more. While barrel life many not be financially concerning for many shooters around the world, it is still good to understand roughly how long your barrel may last until precision starts to decline.

Can a bullet explode in an oven?

Bullets can explode with lethal force if they are stored inside a hot oven.

Do BBs damage a rifled barrel?

The problem is that with its rifled barrel, shooting steel BBs, (like the Umarex 1500 pictured at left) can erode the rifling in the barrel and ruin the gun’s accuracy with pellets. To get around it, you can use lead BBs like Smart Shot (which is copper coated) or traditional Gamo . 177 caliber round lead BBs.
