Don't know why your measurements are different, but I have both styles on my target actions and they both fit.
This is correct , so long as it is indeed a short round back then it will use the same base... A simple cross reference of part #'s from companies such as the vendors on here or say Nightforce will conclude that there are only so many models of one piece short action bases to chose from..
