Ed, last time I used something other than Talley's, I used Warne steel Weaver-style bases with Burris Zee's in low. Worked great as I was looking to add a bit of weight to the 300 WSM. Must have been over 12 years ago. I've used something like 30 pairs of Talley's with no problem, but I do lap them and use a torque wrench rather that making them Neanderthal tight.
