Warne bases are well-made but oversized in comparison to Talley. I tried to use Talley bases on the factory tapped holes with some 30mm Talley rings, but the scope dimensions and the positions of the tapped holes just wouldn't work out. So, I went with Warne which fit anywhere on the dovetail. For the Tikka 595, the Warne ring has a recoil lug that fits into a recess in the forward ring. It is a bit more difficult to get installed than a Weaver base Warne, but you can do it.
I also tried Millett rings -- I believe they are called Angle-Loc. They directly fit the Tikka dovetail and are pretty svelte. I have both 1 inch and 30mm versions. The Warne and Talley vertically split ring design is just so much nicer, though. No questions on whether or not the rings are parallel and in line with the action.
