Yep, a quick update.
I emailed back and forth with Warne and I also spoke with the gunshop I bought the rings at. I’ve not had any luck with being able to use them and the shop has asked me to return them.
I will most likely look at buying a set or two of other mounts and rings to try.
When I closed the rings against each other, the right half of both front and rear rings was a bit smaller diameter than the left rings so I think that could be the issue.
I did not set up a bar or points as suggested above considering that the rings seem out of spec to start with.
I believe that the rings are squeezing the tube causing the issue.
