Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point. 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 ...
The 6.8mm Remington Special Purpose Cartridge (6.8 SPC, 6.8 SPC II or 6.8×43mm) is a rimless bottlenecked intermediate rifle cartridge that was developed by Remington Arms in collaboration with members of the U.S. Army Marksmanship Unit and United States Special Operations Command [6] to possibly replace the 5.56 NATO cartridge in short barreled rifles (SBR) and carbines.
It was designed specifically for the Remington Model Seven Magnum rifle, and intended primarily for long-range hunting use. The difference in velocity between the 7mm SAUM cartridge and the 7mm Winchester Short Magnum (WSM) is less than 50 feet per second; they are almost ballistic twins.
The 6.5mm Creedmoor (6.5×48mm), [6] designated 6.5 Creedmoor by SAAMI, 6,5 Creedmoor by the C.I.P. [4] is a centerfire rifle cartridge introduced by Hornady in 2007. [7]It was developed by Hornady senior ballistics scientist Dave Emary in partnership with Dennis DeMille, the vice-president of product development at Creedmoor Sports, hence the name.
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.
Such shots may be the result of trajectory deviation caused by unexpected changes in wind condition (known as a "wind shift" or "gust"), a muscular flinch of the shooter at the time of the trigger pull, a problem with the firearm mechanism, poor tuning of barrel harmonics, or inconsistency in the ammunition (e.g. bullet/pellet weight and ...
The Barrett Optical Ranging System (BORS) was an integrated ballistics computer manufactured by Barrett Firearms that aids snipers and long-range marksmen in taking precise and accurate shots. The system mounts directly to the riflescope and couples with the elevation knob. With the aid of the BORS, marksmen can rapidly account for temperature ...
In a rifle, the bullet will exit the barrel at about 1,800 feet per second (550 m/s), [14] making it far more versatile than the .30 Carbine or the .32-20 Winchester. In the 1930s it was found to be very effective against steel car doors and ballistic vests, and metal-penetrating rounds were once popular in the United States among highway ...
