Hello all, I just received a Leupold M700 short action "long range" base from Midway. I already have a standard base and When I compare the two I cant see any difference. I checked the dimensions front and rear expecting to see at least some taper compared to the standard base but they measure exactly the same from the point where the bottom of the rings seat to the radius that mounts on the action. What gives?Am I missing something here?? Thanks in advance.
