I am putting together a 22-250 and have an additional 260 Remington barrel I will be swapping back and forth. If I put a 20 MOA base on it will I have any close range scope adjustment or will the average Variable powered Leupold or Burris scope not have enough adjustment if I wanted to dial in a 200 yard or closer zero? I tend to shoot longer distances but usually don't use the 22-250 much over 500 yards. The 260 would be shot as far as I can find a target. I guess the bottom line is what is the minimum distance a 20 MOA base is good for.
