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.
When hunting on private land, virtually all centerfire cartridges with a bullet diameter of at least .243 in (6.2 mm) are legal. On public land, state regulations mandate minimum and maximum case lengths of 1.16 inches (29 mm) and 1.8 inches (46 mm) respectively, plus a minimum bullet diameter of .357 in (9.1 mm), but do not mandate a specific ...
The 270 Winchester Short Magnum or 270 WSM is a short magnum cartridge created by necking down the .300 Winchester Short Magnum and fitting it with a .277 caliber bullet. The correct name for the cartridge, as listed by the Sporting Arms and Ammunition Manufacturers' Institute (), is 270 WSM, without a decimal point. [3]

(or 6.5mm/06) - necked down to accept a 6.5 mm bullet - The 6.5-06 offers ballistic performance between the commercialized 25-06 Remington and 270 Winchester with distinct advantages over both in particular long-range applications through a wide selection of bullets with high ballistic coefficients producing better extended range performance.
The weight of the bullet is a key part of achieving a very high velocity for a rimfire round. It weighs only 17 grains (1.10 g) vs 30-40 grains (1.94-2.59 g) of a typical .22 LR bullet. [ 2 ] The .17 HM2 may or may not live up to its "Mach 2" name, depending on geographic location and conditions, with velocities out of a rifle of 2,100 ft/s ...
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 ...
