Rotaryphile is absolutely correct. The original question specified “no wind” and “normal (standard?) Atmospheric conditions”.

The rise that the shooter observes is due to the sight being adjusted to zero at some distance from the barrel, depending on the range to the target. If the arm was bore sighted only so that the line of sight was parallel to the barrel, there would be no rise observed. However in order for the impact point to coincide with the sight picture at some distance from the barrel, the barrel is pointed slightly upward relative to the line of sight. To the shooter, the bullet does indeed appear to rise above the line of sight, but for the reason stated above.
