Barrel length does not matter, so long as the muzzle velocity is adequate for the twist rate. (Or the twist rate is adequate for the muzzle velocity.)

A 1:7" twist will stabilize a 1.54" .30 caliber bullet at velocities lower than 250 fps. Even a 2" long bullet would be stable at 500 fps.

In this context, barrel length does not matter.

Many modern barrels have twist rates that are unnecessarily aggressive. This is one of those cases.
