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.

The 8.6×70mm variant of the rifle can be differentiated by its slightly longer barrel with a handguard that only has four ventilation holes whereas the 7.62 variant has seven smaller ones. [7] The manufacturer claims that, with 8.6×70mm ammunition, the weapon has a conservative estimate of sub 1MOA accuracy at 1,200 m (1,300 yd).
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 ...
The length of the barrel (especially for larger guns) is often quoted in multiples of the caliber, used, for example, in US naval rifles 3 in (76 mm) or larger. [2] The effective length of the barrel (from breech to muzzle) is divided by the barrel diameter to give a dimensionless quantity.
One of the world’s longest sniper rifles with a length of 1.5 meters, it differs from the typical model as it uses 14.5mm and 12.7mm caliber ammunition. The rifle has a range of 2 km. [9] Hamas first used this rifle in the 2014 Gaza war. The group also stated that these rifles are “evidence of the distinction of its military industries”. [10]
The larger diameter, shorter 6 mm cartridge is optimized for these shorter barrel lengths, and would perform less efficiently from rifle-length barrels. The round's muzzle energy is 831 ft⋅lbf (1,127 J) versus 792 ft⋅lbf (1,074 J) for a 5.56 mm bullet, again from the same 10" standard barrel.
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 ...
Standard length barrel is 16.1 in, featuring a 1:7″ twist (six lands, right twist) barrel with a ferritic nitrocarburized surface conversion which covers the barrel, inside and out, as well as the piston components. Barrel lengths of 10.5″, 12.7″, 14.7″ and 18″ (available for select models) are available.
