While modern firearms are generally referred to by the name of the cartridge the gun is chambered for, they are still categorized together based on bore diameter. [citation needed] For example, a firearm might be described as a "30 caliber rifle", which could accommodate any of a wide range of cartridges using a roughly 0.30 inches (7.6 mm) projectile; or as a "22 rimfire", referring to any ...
The M/88 cartridge was loaded with 2.75 g (42.4 gr) of single-base (based on nitrocellulose) smokeless powder and a relatively heavy, 14.7 g (227 gr), round-nosed ball bullet with a diameter of 8.08 mm (0.318 in). The M/88 bore originally had 7.90 mm (0.311 in) lands diameter and 8.10 mm (0.319 in) grooves diameter.

Bullet drop and wind drift are shown both in mil and moa. The 7.62×51mm NATO has a 3.38 mL (52.0 gr H 2 O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns alike, under extreme conditions. 7.62×51mm NATO cartridge dimensions.
Following the success of the .17 HMR, the .17 Hornady Mach 2 was introduced in early 2004. The .17 HM2 is based on the .22 LR (slightly shorter in case length) case necked down to .17 caliber using the same bullet as the HMR but at a velocity of approximately 2,100 feet per second (640 m/s) in the 17-grain (1.1 g) polymer tip loading.
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 ...
The Taylor KO factor multiplies bullet mass (measured in grains) by muzzle velocity (measured in feet per second) by bullet diameter (measured in inches) and then divides the product by 7,000, converting the value from grains to pounds and giving a numerical value from 0 to ~150 for normal hunting cartridges.
Note **: The horizontal range is the distance traveled by a bullet, fired from the rifle at a height of 1.6 meters and 0° elevation until the bullet hits the ground. [ 169 ] Note ***: The lethal range is the maximum range of a small-arms projectile, while still maintaining the minimum energy required to put a man out of action, which is ...
