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.
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
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 ...
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.
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).
This gun used a standard "fixed" cartridge with 15 lb (6.8 kg) shell, hence a single set of tables applied to all its ammunition. Range tables for US 3-inch field gun , models 1902–1905. Range table for British 3 inch (76.2 mm) Stokes Mortar, 1917
When the competitor arrives at the chronograph station, they provide their pistol and an empty magazine to the Range/Safety Officer who loads a number of rounds into the magazine and fires them through the chronograph to determine the ammunition's velocity. The power factor is verified against the competitor's claimed power factor.
