Forget who mentioned this to me, think it was one of the avratech guys, but the consensus in the thread I had made about this was that barrel rifling doesn't do much if anything for a fsr - the only was that sort of spin seems to work for a fsr is to get it spinning before if his the rifling, thereby also negating the rifling.

I'd just look into a smooth bore .684-5. I have used .685 smooth bore barrels for fsr and they work very well.
