It is thought the word blanc may be used to describe a small white aiming spot formerly at the center of shooting targets. The term point-blank dates to the 1570s and is probably of French origin, deriving from pointé à blanc, "pointed at white". In popular usage, point-blank range has come to mean extremely close range with a firearm, yet not close enough to be a contact shot. Point-blank range will vary by a weapon's external ballistics characteristics and the allowable error at the target the flatter the bullet's trajectory or the larger the target, the longer the point-blank range will be. This results in a weapon that hits too high for very close targets, too low for very far targets, and point blank at some distance in between. If the sights are set so that the barrel has a small upward tilt, the bullet starts by rising and later drops. But if the target is close enough, bullet drop will be negligible so the shooter can aim the gun straight at the target. If the bullet leaves the barrel parallel to the sight, the bullet, like any object in flight, is pulled downwards by gravity, so for distant targets, the shooter must point the firearm above the target to compensate. Point-blank range is any distance over which a certain firearm can hit a target without the need to compensate for bullet drop, and can be adjusted over a wide range of distances by sighting in the firearm. This compensates for bullet drop over a given range. When the bar on the rear sight is raised, the barrel of the rifle points slightly upwards compared to the sights.
