Another factor influencing rate of fire is the supply of ammunition. At 50 rps (3,000 rpm), a five-second burst from an M134 Minigun would use approximately 6.3 kilograms (14 lb) of 7.62 mm ammunition; this alone would make it an impractical weapon for infantry who have to carry a reasonable supply of ammunition with them. For this and other ...
A technique called "Time on target" was developed by the British Army in the North African campaign at the end of 1941 and early 1942 particularly for counter-battery fire and other concentrations; it proved very popular. It relied on BBC time signals to enable officers to synchronize their watches to the second.
9.3×62mm: Very common big game hunting round in Scandinavia along with the 6.5×55mm, where it is used as a very versatile hunting round on anything from small and medium game with lightweight cast lead bullets to the largest European big game with heavy soft point hunting bullets. The 9.3×62mm is also very popular in the rest of Europe for ...
Multiple shots using rounds from the same type and batch are fired to observe how the weapon groups the shots. If a person holds the weapon and shoots it, the grouping measures the combination of the person's skill and the weapon's accuracy. [2] In shotgun shooting, the grouping is also called the pattern or "spread".
Point 2, 3, and 4 describe the time from start of ignition until the bullet leaves the barrel, and can be summarized as the bullet dwell time. [13] In most modern fullbore centerfire rifle cartridges the total dwell time lies around 1.0 to 1.5 milliseconds, while the slower .22 Long Rifle round has a dwell time of around 2.3 milliseconds when ...
For example, in Denmark rifle ammunition used for hunting the largest types of game there such as red deer must have a kinetic energy E 100 (i.e.: at 100 m (110 yd) range) of at least 2,700 J (2,000 ft⋅lbf) and a bullet mass of at least 9 g (140 gr) or alternatively an E 100 of at least 2,000 J (1,500 ft⋅lbf) and a bullet mass of at least ...
For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
Thus the optimum rate of twist for this bullet should be approximately 12 inches per turn. The typical twist of .30-06 caliber rifle barrels is 10 inches per turn, accommodating heavier bullets than in this example. A different twist rate often helps explain why some bullets work better in certain rifles when fired under similar conditions.
