oldrookie, the bullet doesn't really rise - it starts dropping from the time it leaves the bore - relative to the line of bore. A scope generally sits centered about 1.5" above the bore so line of sight is always above line of bore initially. A picture is worth a thousand words so:

Hope you can get an idea from that. You'll see that the bullet path does intersect the line of sight at two points - a near-range point and again at the zeroed range You'll also see that, even though the bullet is dropping, it actually does travel above the line of sight between those two intersections.

2" high at 25 yards might be good for a near zero at 100 yards - but no guarantee.
