Leupold Dual Dovetailbases and Low rings(0.65") will fit a 2.5-8x Leupold nicely.
Have a look at the latest u.s. GUNS magazine. It has the latest 325WSM set up with this combination on the front page.
I have a 2.5-8x in dual dovetails on a SaM70(22/250)with superlowrings(0.55"). I got the front rings from 2sets of std.superlows.But the superlows/2.5-8x combination may not fit the WSM reciever,because the screws are about 6mm further apart. than the std.SaM70 so the bases may hit the scope.But you may be able to get around that by:
- chamfering the front of the front base and the rear of the rear base.If you could do that, It would look hot!
-The other option is use the longer tubed 1.75-6x or 1.5-5x Leupold with the superlows.
The Conetrol system looks good also.
