Therefore with a 12-gauge, it would take 12 balls of lead of the same size as the 12 gauge shotgun's inner bore diameter to weigh 1 pound (453.6 g). [5] The term is related to the measurement of cannons, which were also measured by the weight of their iron round shot; an eight-pounder would fire an 8-pound (3.6 kg) ball. Therefore, a 12 gauge ...
Typical 8 bores weighed 15 to 16 lb (6.8 to 7.3 kg), and fired a 1,250 gr (81 g) conical bullet at around 1,500 ft/s (460 m/s) or an 860 gr (56 g) spherical ball at around 1,650 ft/s (500 m/s), both with 10 to 12 drams (17.72 to 21.26 g) of black powder, [1] although sometimes heavier charges of 14 drams (24.82 g) were used, generally in Africa.
The diameter of the a Gauge N is the diameter of a Ball what is maid out of the equal parted N part of a imperial pound of soft Lead. So a 12 Gauge 18.53mm (0.729 inc) is bigger as a 16 Gauge 16.83mm (0.663 inc) The definition today:
A ball gauge is an instrument used by the umpires in cricket to check whether the size of a cricket ball meets the standard measurements mandated by the Laws of Cricket.It is usually in a form somewhat like a pair of handcuffs with two connected rings: one ring has the minimum acceptable diameter, through which the ball should not pass; the other ring has the maximum acceptable diameter ...
A round shot (also called solid shot or simply ball) is a solid spherical projectile without explosive charge, launched from a gun. Its diameter is slightly less than the bore of the barrel from which it is shot. A round shot fired from a large-caliber gun is also called a cannonball.
This is a list of firearm cartridges which have bullets in the 11 millimetres (0.43 in) to 11.99 millimetres (0.472 in) caliber range.. Length refers to the cartridge case length
For example, the barrel of a 12-gauge shotgun is equal to the diameter of a 1/12 of a pound lead ball (0.729 in) and a 20-gauge can fit a 1/20 pound lead ball (0.615 in). Using this method, a .410 bore is equivalent to a (hypothetical) 67-gauge, instead of the incorrectly labeled 36 gauge (0.506) in Europe and South America. [14] [15]
The 7.92×57mm Mauser (designated as the 8mm Mauser or 8×57mm by the SAAMI [2] and 8 × 57 IS by the C.I.P. [3]) is a rimless bottlenecked rifle cartridge. The 7.92×57mm Mauser cartridge was adopted by the German Empire in 1903–1905, and was the German service cartridge in both World Wars. In the first half of the 20th century, the 7.92× ...
