Melvin Forbes designed these rings and sold the rights to talley so he has used this style ring since nulas inception
I have used them countless times and switched scopes back and forth and never had one scratch or dent a scope tube but ther is always a first.

Gene do you lap these before mounting your scopes. I never have. It's almost like the sharp inside corners of either the ring caps or the lower rings dug into the scope tube. Maybe lapping off those corners is the answer. I really like the design of these things and I don't want to ditch them if there is a relatively easy fix for this.
