Thanks, all, for the comments.
I ordered some S&Ks, but I'll keep in mind that Talley would likely be able to make their rings work on my receiver. Worst case I'll send it over to them if I can't find a solution.
As an aside, when I got the rifle back from the smith it had Leupold windage adjustable bases. When I removed the action from the stock to visually inspect the bedding job, one of the screws sheared in half. So much for the Leupold bases, as that's the second windage screw I've personally seen broken on those. They may work for others for a lifetime, but I'm not sold on them as of now.
