You don't have any drop at 25 yards, your scope is mounted higher than the bore of the rifle, probably about 1.75 inches... 
Now, I would suggest sighting in about 2 inches high at 100 yards, then you can hold dead on the lungs of a deer and be no more than about 2.5 inches high or low out to about 225 yards...Out to 250-300 you would need to hold a few inches high to hit where you want...
Have fun!!!

Put another way, it's not "drop", but bullet leaves the gun below the scopes line of sight, you set it to "climb" up to that line of sight at 100 yards, which is the right thing to do.
When it leaves the gun it's lower than that and a25 yards given it time to climb yet.
If you did that same thing, but at 125 yards, you probably see that you hit a bit high.

Generally, bullets to not rise or climb after they leave the barrel. in fact they start t drop as gravity is affecting them. You sight in your rifle to compensate for gravity so if a bullet rises it is because the muzzle is raised beyond horizontal to compensate for gravity at distance. A bullet will not rise above the axis of the barrel. It is no different than a quarterback during the passing of a football. For a long pass he throws the ball higher than the sweet zone of the receiver to gravity will put it there when it reaches him.

Spend some time on balistic calcuators. Nikon Spot On is one. 1.75 is lower than I would expect, but not alot.
How your scop is mounted, effects it. But I don't expect it to equal the height at 25 yards either.
Play with a calculator. Do some some shooting to know your rifle. Decide what you can live with. I hunt in heavy bush and like a tight path. Field hunters, shooting lungs, may go with a bigger arc, or point blank range.
