    If the coating isn't exactly the same thickness throughout the entire surface on the inside surface of the rings you torque the rings down on the high spots not the whole surface as intended. over time and being subjected to recoil and vibration of handling and hauling plus gravity pulling down on the scope at some time sitting there it gave way and slid. I may be totally off but

    1 Scope moved
    2 scope was torqued to spec
    3 have coating residue on scope
    4 now can torque rings down on scope but until cleaned out have coating residue that needs to be cleaned out or torqueing on moving matter.

Maybe yours was at the end of a tooling set. EVERY set of Talleys I have done looks like the one in the picture the other fellow posted, at best 20% contact. Clearly any explanation, other than a haunted safe, you disagree with so most of us that are trying to help are at a loss.

      Good luck with your issue. I hope you get it worked out and back to shooting soon.

      I get what you're saying, & I am appreciative of the input, but I'm not lapping a set of $200 rings when the manufacturer says it deosn't need to be done AND they'll void the warranty if I do.
      Having said that, I'm thinking the coating is the culprit (which would be fixed if lapped but again, read above). I've never owned coated rings & I've never had this happen before so the coating is the only common denominator here.
      Talley has been great & mailed out a new set yesterday (same day I contacted them). I'll contact them again prior to installing them about the coating & about lapping, especially due to the coating. I will keep this post up to date as things evolve.

      ***ETA***
      I just emailed Talley again w/this:
      "Everyone I've discussed this with has had 2 opinions:
      1) the rings need to be lapped
      2) the coating is the issue

      I see y'all advice against lapping, & void the warranty if done, but what about the rings w/the coating? Surely it can't be applied 100% perfect thickness, or can it?

      I'll get these back to y'all quickly so y'all can check on your end what possibly went on. I'm going to put my micrometer on these & check the thickness thoroughly & do the new set as well prior to installation."

      I'll let y'all know what they say!

        I’ve never lapped a set of rings and I have several rifles that shoot 1/4-1/2”.

          Neither have I & they've all shot MOA @ worst, 1/2 MOA @ best. This gun shot a 1.75" group @ 200yds prior to this happening & I was still breaking it in/ finding exact ammo it liked & it was getting better each outing.

            I wonder if you received mis-labeled 35mm rings

              Would they have even tightened initially if they were 1mm too big?

                I think they would. I have the same scope on two different rifles, there is enough gap between the upper/lower mating surfaces to close 1mm.

                I would be curious how much gap there is on yours between the mating surfaces (each side of scope).

                  But what could it possibly hurt?

                    Found the issue. The dang rings broke in half!!!! This is just insane. It appears it's a design flaw. The rail mount pushes into the bottom of the ring and causes an unexpected upward force that it appears the ring couldn't handle. I'm at a loss here.

                      Well there's your problem alright!
                      Dang.

                        Am I the only one that thinks this does NOT look like billet aluminum?

                          Hard to say due to coating and angle of break. Those 40$ lightweights are looking pretty good now! At least you know what it is.

                            I believe if they were billet then they would've bent not broke. I believe they are cast even though they tout them as billet.

                              The only upside:
                              looking @ the ring marks from the paint that transferred onto the scope, it had full ring contact except for where the top & bottom of the rings mated. I'd estimate ~95% contact.

                                That square corner on the side clamp pocket is a weak design, it provided a shear point for the ring. I would get your scope checked out as well, that may have bent the tube and may not be noticeable yet. The reason I say that is I doubt both mounts busted at the same time which could have put the scope in a bind. I would also tell Talley your scope may be damaged from the busted mounts.
