It appears to me that a much slower barrel twist rate is not an advantage.
First is obtaining very light FWC light bullets. Most of the big commercial casters make 148 grain lead bullets for target...and they work very well. Plus, try & finds swagged lead 100 grain bullets.
Two. A much slower twist rate as suggested goes against the grain (pun intended!) of what most PPC revolver shooters know. And have proven.
It is much easier to use a faster twist rate and a lower velocity for 148 grain FWC's to achieve accuracy, than push a much lighter bullet of whatever construction at a higher velocity. It appears that a faster moving light FWC has little time to really stabilize in flight. Plus, this much lighter bullet will have a significantly smaller driving band to create accuracy with such s slow spin. It appears that this concept is entirely anathema to accuracy.
PPC is all about timed accuracy, & has no power factor. PPC revolver shooters have solved the accurate load problem. It is the human operator that determines winners.....
