Succinct

In a Facebook conversation that Erin asked me to attend...

I'm flailing around trying to explain to a friend of hers about rifling twist and the AR.

Because there's lots of variables I'm hopping around trying to cover each in turn when someone else chimes in with, "A given bullet stabilizes at a particular RPM. The RPM is a function of the twist rate and the muzzle velocity. More velocity equals more RPM. The practical gain from more velocity is pretty minor compared to the gain from a faster twist though."

Yup!

It's all about the revolutions.

Still need more maths than I have to calculate how many you need.
