Why don't you place a target downrange and find out

I zero at 50 yards, and am "close enough" out to 250 yards.  
At real close range (like inside a room) POI will be a few inches low (sight distance over bore)

dead on at 50y makes it about 1.5 inch high at 100y so if you have it dead on at 25y thats going to be even higer at 100y because on the distance between the line of sight and the bore.. .  You need it about 1.5 inch low at 25y so your on at 50y, 1 to 1.5 high at 100y and still only maybe 1 inch low at 200y.

With a 25 yard zero:

25 = 0"
50 = +2.3"
75 = +4.2"
100 = +5.7"
150 = +7.6"
200 = +7.8"
250 = +6.2"
300 = +2.4"


With a 50 yard zero:

25 = -1.1"
50 = 0"
75 = +0.8"
100 = +1.2"
150 = +0.8"
200 = -1.2"
250 = -5.2"
300 = -11.2"
