The required RPM is a function of bullet length, yes, but getting that RPM only has two variables.... barrel twist rate and velocity. Since the twist rate is fixed (in a given barrel), the required RPM can only be achieved with more velocity.

My 2cents - I had a 357 max barrel (forget how long, but rifle legal) that would shoot 357 max perfectly, 357 mag so-so, and 38 special was the best shotgun group I'd never want to see. You are asking a low pressure round to jump a VERY long way to enter the throat. In that time a lot of pressure has moved around the bullet, maybe even causing a Major wobble and accuracy is going to pay.
Stability is a factor of bullet weight, velocity, and how you hold your eyes when you squeeze the trigger
Honestly, I have all the barrels I want or could ever need..... wait, look, there's another!!
