Note: Use of this table for estimating bullet masses for historical large-bore rifles is limited, as this table assumes the use of round ball, rather than conical bullets; for example, a typical 4-bore rifle from circa 1880 used a 2,000-grain (4.57 oz; 129.60 g) bullet, or sometimes slightly heavier, rather than using a 4-ounce (110 g) round ...
The concept historically originates from the idea that a lesser hit with a harder hitting caliber will be more likely to end a firefight in a real life situation. However, modern ballistic studies have shown no noticeable difference in terminal performance correlating to the recoil difference between typical minor and major handgun calibers. [7]
Cartridge adapters have also been made to use .38 caliber handgun cartridges with bullet diameters of approximately .357-inch (9.1 mm) in .35 caliber rifles designed for bullets of .358-inch (9.1 mm) diameter. [3] Supplemental chambers in .22 caliber, and potentially .17 caliber as well, pose a special problem not shared by larger calibers.
m = bullet mass in grains (defined as 64.79891 milligrams) s = gyroscopic stability factor (dimensionless) d = bullet diameter in inches; l = bullet length in calibers (that is, length in relation to the diameter) t = twist rate in calibers per turn; Also, since one "caliber" in this context is one bullet diameter, we have:
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 ...
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
The difference in .38 Special bullet diameter and case diameter reflects the thickness of the case mouth (approximately 11/1000-inch per side). The .357 Magnum evolved from the .38 Special. The .357 was named to reflect bullet diameter (in thousandths inch), not case diameter. "Magnum" was used to indicate its longer case and higher operating ...
Some of the revolver cartridges in this caliber are: 7.62×38mmR is used only in the Nagant M1895 revolver..32 Long Colt – originally chambered for small-frame Colt revolvers and the Marlin model 1892 rifle, this cartridge uses a heeled bullet with a case the same diameter as the major diameter of the bullet. It shares dimensions with the .32 ...
