Sighting in a firearm is an important test of the ability of the firearm user to hit anticipated targets with available ammunition. Pictures or silhouettes of intended targets are less suitable for sighting in than high contrast shapes compatible with the type of sights on the firearm. Contrasting circles are commonly used as sighting in ...
Benchrest shooting with a Mauser rifle. This is an example of the non-competitive use of benchrest techniques. Neither the rifle, the rest, nor the bench shown would be found in formal competition. They show, rather, adaptations of benchrest ideas for the more common hunting rifle. Rifles are usually custom-made with extreme accuracy in mind ...
The zero range, , is important because corrections due to elevation differences will be expressed in terms of changes to the horizontal zero range. For most rifles, is quite small. For example, the standard 7.62 mm (0.308 in) NATO bullet is fired with a muzzle velocity of 853 m/s (2800 ft/s).
On firearms, bipods are commonly used on rifles and machine guns to provide a forward rest and reduce motion. The bipod permits the operator to rest the weapon on the ground, a low wall, or other object, reducing fatigue and permitting increased accuracy. Black powder also called gunpowder: A mixture of sulfur, charcoal, and potassium nitrate.
Comparison of milliradian (mil) and minute of arc (moa).. Since adjusting the point of impact to match the point of aim is relatively simple with any type of adjustable sights, the primary goal of accurizing is to increase the precision of the firearm, which is generally measured by looking at the dispersion of a number of shots fired at the same point of aim.
Boresighting is a method of visually pre-aligning a firearm barrel's bore axis with the target, in order to more easily zero the gunsight (optical or iron sights). The process is usually performed on a rifle, and can be accomplished either with the naked eye, or with a specialized device called a boresighter. [1]
The Mauser KKW (Klein Kaliber Wehrsportgewehr) cadet rifle is a single shot, ... (109.4 yd) during the factory zeroing (Anschießen) of the sight line and firing test ...
A benchrest rifle, also colloquially called a "rail gun", is a rifle with its barrel and action mechanism built into a machine rest, used mainly for benchrest shooting. The rifle has no proper stock and its base uses adjustable feet to provide a stable position on the bench, and the rifle is finely aimed with horizontal and vertical adjustments ...
