Take a zero of 75 yards, a sight height of 1.5", and a MV of 1250fps.
The bullet will reach the top of its arc between 40 and 50 yards, 1.2" above the point of aim. At 75 yards, the bullet will have dropped back down to the point of aim (the "zero"). At 100 yards, the bullet will have dropped another 3.2" below point of aim.
The 25yd zero seems very practical also for a plinking or closer-range squirrel-getting, as the bullet stays within a half inch of POA out to about 65-70 yards. I don't mind having a little more mid-range "arg" to my shots, so I tend to zero a little further.
