what does rifling cause the projectile to do

Rifling causes the projectile (bullet) to spin around its long axis as it travels down the barrel and through the air.

Quick Scoop

• Rifling are spiral grooves cut inside a gun barrel.

• These grooves grab the bullet and make it spin like a thrown football.

• The spin gives the bullet gyroscopic stability, so it does not tumble end-over-end.

• Because of this stability, the bullet flies straighter, with better accuracy and effective range.

What does rifling cause the projectile to do?

In simple question-answer form:

• Q: What does rifling cause the projectile to do?
  A: It causes the projectile to spin, stabilizing it in flight and improving accuracy.

Without rifling (a smoothbore barrel), a bullet tends to wobble and can tumble, which makes it much less accurate and limits its useful range.

In many basic ballistics and forensic science questions, the correct one- word answer to “The purpose of rifling is to make the bullet do what?” is: spin.

TL;DR: Rifling makes the projectile spin, which stabilizes it, reduces tumbling, and increases accuracy and effective range.
