I've a Thompson Center Venture in 204, with the rail in the receiver where the scope mounts.
I'm buying the DNT optics The One scope. I've contacted two scope ring manufactures that I have faith in as to what height I need to keep the scope as close to the barrel as possible.
Here's what I was told: Warne Tech said a .275 should work, Seekins said a 0.92, any suggestions? Both are returnable if they don't work, the formula on this site is not adding up to me.
