Accurizing is the process of improving the accuracy and precision of a gun (firearm or airgun). [ 1 ] For shooting sport , accuracy is the gun's ability to hit exactly what the shooter is aiming at, and precision is the ability to hit the same place over and over again in a repeatable fashion.
Centerfire ammunition is often handloaded, with very careful selection of components so maximum precision can be obtained. Lighter weight bullets and lower velocities are often selected to minimize recoil and improve precision. For any given handgun or rifle there is an optimum combination that delivers the peak or maximum possible accuracy.
The TrackingPoint XS1, a precision guided firearm. PGFs are fully integrated systems consisting of a rifle, networked tracking scope, guided trigger and precision conventional ammunition based on standard caliber bolt action or semi-automatic rifles. Wireless connectivity allows PGFs to integrate with local and wide area networks to provide ...
Precision Pistol Competition (PPC), originally and still known as Police Pistol Combat in North America, is a shooting sport focusing on precision shooting from a variety of stances (standing, kneeling, sitting and prone) at varying distances (3, 7, 15, 25 and 50 meters or yards), including shooting from behind an obstacle.
The tightness of the grouping (the proximity of all the shots to each other) is a measure of the precision of a weapon, and a measure of the shooter's consistency and skill. [1] [2] On the other hand, the grouping displacement (the distance between the calculated group center and the intended point of aim) is a measure of accuracy.
Gun B has poor consistency, but good accuracy. [citation needed] Figure 3: The mean points of impact for guns A and B (case 2) A more realistic possibility is shown in Figure 3. In this case, assuming that each series had the same consistency as those shown in Figure 1, gun A shows good consistency and accuracy, and gun B is poor on both counts.
Rifling of a 105 mm Royal Ordnance L7 tank gun Conventional rifling of a 90 mm M75 cannon (production year 1891, Austria-Hungary) Rifling in a GAU-8 autocannon. Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy.
CEP is not a good measure of accuracy when this distribution behavior is not met. Munitions may also have larger standard deviation of range errors than the standard deviation of azimuth (deflection) errors, resulting in an elliptical confidence region. Munition samples may not be exactly on target, that is, the mean vector will not be (0,0).
