BUT, if we asume a few things, such as a velocity of 2700 fps, a ballistic coefficient of .241 (round nose bullet) and a scope height of 2" over the bore, you could use the following data:

25 yds - 0.4 inches low.
50 yds - 0.8 inches high.
100 yds - 2.2 inches high.
150 yds - 2 inches high.
200 yds - 0.

Note that the numbers above indicate the bullet should be hitting almost a half-inch low at 25 yds to get these results. You really should shoot the gun out to 100 yds at least to confirm where it is hitting.

But to answer your question, if the gun is truly hitting dead on at 25 yds, it will be about 4.5 inches high at 150 yds.
