Found a link for you to maybe help explain the differences. Just to much information to type so try the link for your answer. Hope it helps you..Barrel Twist in the AR-15 | The Shooter's Log

In a nut shell.

Slower twist, 1 turn in 12" for light bullets.

Faster twist, 1 turn in 8" for heavy bullets.

I'd never get anything slower than a 1:9" twist barrel for shooting 5.56/.223.
