The accuracy should not be confused with the “rightness” since the latter is a purely ballistic quality is derived from the characteristics of the rifle is fired munitions; it therefore concerns a wider range of elements that come into play.
The compatibility between barrel length, caliber and rifling pitch, velocity of the projectile, its weight and shape; all these elements are the ingredients that define the correctness of a weapon. A ‘weapon’ not right ‘generates a high dispersion of projectiles launched, while maintaining unchanged the pointing, so the shot will never be accurate. In fact, some rifles denounce sometimes yield uncertain because they lack in correctness. When a rifle performs a constant shift with respect to the point of aim, you can correct the error by activation of aims, through a new and accurate collimation, between point of aim and point of impact of the bullet.
But if the finding of the shots that do not satisfy us is due to pointing errors, and the problem is not so in the rightness of the weapon, the only remedy is to resort to the weapons sights more precise and effective, facilitating the targeting mainly in place by strong shots away.
As for weapons for hunting and shooting, each pointing system has special characteristics of performance, making it preferable for a particular purpose, in connection with the shooting that can be targeted against stationary or moving, the distance of the target and the its speed of movement, the time available for the target, to the characteristics of the trajectory of the projectile.
The mechanical parts are the more traditional method of tracking and simple that it is used in rifled guns, and that is typical of military origin. The device “of stand up,” can be fixed sight, adjustable slider or dial. Land lines are formed by the viewfinder and a standing place on the socket, said skim coat, bearing the rear sight. The viewfinder is fixed, may have a quadrangular section, triangular, circular, in the form of pearl, thread. In this case, the perfect tracking is obtained by aligning the rear sight, the viewfinder and the center of the target.
Shotgun target organ diottraIl system is not very accurate because it is simply a small error in the alignment of the three elements to prove a significant shift of the shot; still allows a pointing among the fastest, suitable for shots of no more than 80-100 m. In some shooting and hunting rifles, the rear sight is replaced with a diopter. Formed by a metallic device adjustable, fixed on the back of the castle of the rifle. At the height of the device is a disk with a small hole in the center, where it passes the line of sight of the target. You simply put in focus the viewfinder and the target to achieve a proper pointing. The diopter focus and tallies the only two items instead of three (notch, sight and target), in addition to the fact that the hole is closest to the eye of the normal rear sight. Generally the pin is used for the shot in the polygon, in particular for airguns.
Pointing Devices fast as the Single Point Kiln Acre and others, are optical devices for the shot against moving targets. Shape similar to a telescope, connected to the gun with the usual attacks, they can give you a view of the target normal or slightly enlarged. The collimation is done by the central red dot, which remains visible shooting with both eyes open, even in poor light conditions. Its defect is represented by the precision that is very relative, which limits the field of application only for a short distance shots.
The telescope on the other hand, is an optical instrument for observing objects at great distances, allowing to increase the visual size compared to observation with the naked eye.
The telescope enables to send the bullet in a vital point of the body of the wild, to bring it down on the spot. Avoid sunlight reflections that form the common organs of sight, visual defects of the shooter medians a diopter correction, enhances the ballistic qualities of the weapon and ammunition.
The optics can not completely eliminate human error, much less atmospheric effects that affect the trajectory of the bullet, nor replace humans in the calculation of the correction imposed by pointing the shot.
The presence of the lens is intended to be counterproductive in the shooting to fast moving targets, shooting in sudden, from a short distance, in hunting and in the dangerous animals in the bush, in framing the target quickly and for the reduction of the visual field. The modern trend has however allowed many companies to develop “from optical beat”, able to overcome the above critical.
