Historically, this table has been referred to as a "drop table." The drop table can be generated empirically using data taken by the shooter at a rifle range; calculated using a ballistic simulator; or is provided by the rifle/cartridge manufacturer. The drop values are measured or calculated assuming the rifle has been zeroed at a specific range.
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load ...
Miller twist rule is a mathematical formula derived by American physical chemist and historian of science Donald G. Miller (1927-2012) to determine the rate of twist to apply to a given bullet to provide optimum stability using a rifled barrel. [1]
The average ballistic coefficient of the 419 grain (27.15 g) is 0.945 over 3,825 yards (3,500 m). Jamison International stated the G1 BC of this bullet on their websitein 2009 at 0.940. Currently (2024) the average ballistic coefficient of the 419 grain (27.15 g) is stated by CheyTac USA at 0.949 over 3,500 yards (3,200 m). [14]
The velocity gain over the .375 H&H Magnum works out to be about 240 ft/s (73 m/s) and an increase in maximum point blank range of about 25 yd (23 m) with bullets of equal weight. The .375 Weatherby Magnum fires a 270 gr (17 g) at 2,940 ft/s (900 m/s) generating 5,181 ft⋅lbf (7,024 J) and a 300 gr (19 g) at 2,800 ft/s (850 m/s) which ...
For small arms, the magnitude of the Coriolis effect is generally insignificant (for high powered rifles in the order of about 10 cm (3.9 in) at 1,000 m (1,094 yd)), but for ballistic projectiles with long flight times, such as extreme long-range rifle projectiles, artillery, and rockets like intercontinental ballistic missiles, it is a ...
Extremely high initial velocity (over 4,000 ft/s 1,200 m/s), flat trajectory and very low recoil are the .17 Remington's primary attributes. It has a maximum effective range of about 440 yards (400 m) on prairie dog -sized animals, but the small bullet's poor ballistic coefficients and sectional densities mean it is highly susceptible to ...
