A big-game hunting rifle is considered accurate if its shots fall within 1.5 MOA (≈ 0.5 mil), while a rifle intended for small animals is expected to have an accuracy of 1 MOA or less (under 0.3 mil, also known as "sub-MOA"). [1]
For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
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 .300 Winchester Magnum (also known as .300 Win Mag or .300 WM) (7.62×67mmB, 7.62x66BR) is a belted, bottlenecked magnum rifle cartridge that was introduced by the Winchester Repeating Arms Company in 1963. The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action.

The three main technologies employed for long-range shooting—the bolt-action rifle, telescopic rifle scope and machined cartridge ammunition—were developed in the nineteenth century. The first bolt-action rifle was produced in 1824 by the German firearms inventor Johann Nicolaus von Dreyse. The first documented telescopic rifle sight was ...
By comparison, the 5.56×45mm NATO cartridge, used in the M16 and M4 rifles, produces between 1,200–1,300 foot-pounds force (1,600–1,800 joules), while the .308 Winchester, a favorite for hunters, police, and military snipers, produces between 2,000–3,000 foot-pounds force (2,700–4,100 joules) depending on the load used.
Modern comparisons to the .44 Henry rifle's ballistics would include such large-bore handgun cartridges as the 200 gr .45 ACP, and 200 gr .44 Special. Due to the vast advances in propellant and metallurgy technology, these latter can nearly achieve the Henry Rifle's velocity from a handgun, and do not even require the long barrel of a rifle to ...
