It depends on where the manufacturer centered the erector and how the top of the receiver is illed. They seem to usually center them in the travel, so your 60MOA travel on a 20MOA base is probably about 10 MOA off of the bottom.
That said, I've got a R700 that with a 30MOA base on it my Nightforce Scopes are still able to get a 100 yard zero, (both scopes I've had on that rifle have been able to get a 100 yard zero less than one turn off of the bottom) whereas putting those same scopes on my Defiance action with a 30MOA base and you cant get to a 100 yard zero.
The answer is that it depends, but with a scope with that much adjustment why bother with a 20 MOA base, unless it's just what you have? Shooting something as pedestrian as a 175SMK in a moderate 308 load will get to 1000 yards with about 36MOA from a 100 yard zero, better bullets and more MV get you there in about 30MOA.

With my Dasher all my 20MOA bases works at 100 and 1000 Put 25MOA rings on one and they were too much for 100. Larry
I don't think it will having only 60 moa. As more folks get into the long range game adjustable bases are the best option but a few folks that made them have quit leaving a big hole in the market. One new company has some prototypes out for testing but I have not heard a peep how they are doing or price point.
Bases only give the ability to correct the lack of Moa of adjustment in the scope

Larry, in many cases I'd say that bases allow you to recover elevation that the scope manufacturer has made useless. I think the two scopes that allow you to get it all back without bases are Steiner (at least I think the MX5i zero stop does) and I know the USO turret with the big one turn knob (forget what they call it). All the others seem to have your 100 yard zero pretty well in the middle of the erector range, which effectively results in losing ½ of the adjustment range.
Sorry it not just a base . the one you are talking about has ben out for years bench rest shoot with one similar they do it because their scope adjustments are froze. Larry

What are you trying to say? It won't work with anything other than a frozen reticle scope on a bench rest rifle?
I said it not a base. T
The question was 20 MOA base. And that is what I answered to. Never did I say it wouldn't work with other scopes. Larry

What part of "option" don't you understand?
Nothing was said abot optins
I went back and read what he ask I didn't see anything about options. A normal scope with 20 MOA base will shoot 100 to 1000 yards. Larry
