only reason i can think of is you'll wear the bore out faster

If a bullet doesn't spin fast enough it's not stable. If it spins too fast it's not stable and could rip itself apart. It is a balancing game of the speed weight and durability of the projectile as to what the ideal twist is. In ar15s it's generally between 1 in 6 and 1 in 12 depending on bullet weight.

How does spinning too fast make it unstable?

Centrifugal forces, like how clothes start to separate towards the sides of a washing machine or how when you make a sharp turn in your car you feel your blood shift to one side. Except x100.

Besides reducing velocity of the bullet and increasing wear of the rifling then no.
