Welcome marlin!

I have not heard of Warnes for Rugers.

Like tophet, I had some trouble initially with Warnes on a CZ550 9.3x62. With the front ring set all the way forward the mount fouled the front uncut portion of the dovetail just a bit, and repeatability was nil.

Once I set the ring back a bit and use the same re-attachment procedure, I get excellent repeatability.

I will be curious to see what Warnes look like on the Ruger.
