I got the 308, according to Warne the medium rings have about .435" of clearance. I tried to find dimensions on the scope I ordered but didn't have any luck. (Zeiss 4.5-14x50mm AO Conquest 1") I do know that the high rings have something like .535" of clearance.
Waffen, thats a great looking rifle, I love that stock. Hopefully my 308 will be a shooter too.
