Dooshie,
What happens is that a bullet construction is designed for a maximum spin (RPM) when going down range. If that spin rate is greatly exceeded, the bullet can literally fly apart on the way to the target. it can also become unbalanced and cause it to veer off course making the accuracy suffer.
Bullet construction is often a compromise, especially if they are tailored for something other than target shooting. If the bullet is made with a tough jacket so it can be pushed very fast, and therefore high spin rate, at low velocity it won't necessarily expand when it hits an animal and suffer poor killing ability. If it needs to expand with lower velocity, such as with the 300 blackout, then if pushed to magnum velocities, it can suffer from the RPM issues. Likewise, if a magnum bullet is loaded at low speeds, it can have insufficient spin to have stable flight.
Target shooters, such as NRA High Power, look at everything as part of an overall system and choose a barrel with a specific twist depending on what bullet they are shooting, optimizing the spin rate to have the bullet stabilize in flight and high enough speed to minimize wind deflection.
Hope this helps with the WHY.
