I've worked with both in .308 and .260. Barnes recommends seating 0.050" off the lands. So I started there and worked up some hunting loads using the OCW process. Got 0.5 - 0.90" 3-shot groups @ 100'. Never messed with seating depth to see if I could improve accuracy. My understanding is the rings were added to the original Barnes-X bullet design to reduce bearing surface, chamber pressure and copper fowling. Best accuracy is usually around the max load based on what I have read and my experience. Best of luck and have fun!
