There is a formula for this, anyone know some links or data?

Can this data be used to tailor a load for a given rate of twist in an existing rifle?

If your thinking about conventional sptizer type bullets then http://www.bergerbullets.com can fine tune it for you.

But consider that a fast twist is the side to error on and that if monolithic bullets catch on they will require a faster twist for the same weight.
