Shooting at close range indicates a cylinder bore barrel to deliver a wide grouping, while for hunting at longer distances such as 50 yards or meters, a choke is recommended to constrict the scattering for a tighter pattern. [3] In archery, a shot grouping is the result of one person shooting multiple arrows at a target.
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
Observe that if the rifleman does not make a range adjustment, his rifle will appear to hit above its intended aim point. In fact, riflemen often report their rifle "shoots high" when they engage a target on an incline and they have not applied the rifleman's rule. Equation 6 is the exact form of the rifleman's equation.
It is widely accepted within interdisciplinary circles that for a standard rifle firing full-powered cartridges (e.g. .308 Winchester), "long range" means the target is more than 600 m (660 yd) away, [citation needed], while "extreme long range" is generally accepted as when the target distance is more than 1,000 m (1,100 yd) away from the shooter.
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.

The International Confederation of Fullbore Rifle Associations (ICFRA) is the international association for the fullbore rifle shooting sports of target rifle ('TR') (called 'Palma' rifle in the US) and F-Class, which are long range competitions shot at distances between 300 and 900 meters or 300 to 1,000 yards depending on the range.

Precision Rifle Series (PRS) is an American long-range and precision rifle-based shooting sport derived from practical shooting. The series have a championship style where competitors collect points from 45 matches spread across nearly twenty U.S. states , and thereby are ranked across the nation. [ 1 ]
