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 ...
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 ...

Chamber illustration indicating the various sections of a typical rifle chamber. The freebore is the cyan colored section just ahead of the neck. In firearms, freebore (also free-bore, free bore, or throat) is the portion of the gun barrel between the chamber and the rifled section of the barrel bore. The freebore is located just forward of the ...
A cleaning cord often has one or more integrated brushes to help clear away more stubborn contaminants, and may also be used to apply lubricants. An assortment of cleaning rods: A short cleaning rod with a brass brush attached, a foldable cleaning rod with a nylon brush attached, a cleaning kit for a shotgun (note the thicker rod), and some ...
In the Lee-Metford rifle, the Morris Tube and the .297/230 cartridge were not particularly accurate and were replaced after 1908 by a new .22 in (5.6 mm) tube firing the rimfire .22 Long Rifle cartridge which was more accurate, quieter and much cheaper. [1] [2] [4] [5] [6]
The normal factory load consists of a 200 grain round-nosed bullet with a muzzle velocity of 2080 feet per second. This 200 grain bullet is nearly 18% heavier than the .30-30's 170 grain bullet, and has a 16% larger frontal area. This gives it a substantial increase in power over the .30-30, especially when used on larger game species.
Typically, many rifles use thread diameters in the range between 25–27 mm (0.98–1.06 in). [citation needed] Many older rifles from the first half of the 20th century use a thread pitch around 2 mm (12.7 TPI), while many modern rifle use thread pitches around 1.5 mm (16.93 TPI). Fine threaded systems intended for hand tightening typically ...
