Thread: Is there a down side to fast twist barrels?

The difference a faster twist makes on projectile expansion is sweet F#&k all!

This is true. There is a myth about that driving a bullet faster in a slow twist barrel will stabilize a bullet better - not true. Some bullet shapes will be slightly more stable at higher velocities but others not. However there is a big difference with bullets that go transonic within the target range and some subsonic bullets shapes require more stabilization but not all. This is why subsonic 22lr's are more accurate than HV's.
