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 ...
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 ...
In the above formula, "36" is the conversion factor between yards and inches. Conversely, the group size of 1 arcminute at 100 yards (the most commonly used sighting-in distance in North America ) can also be calculated:
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]
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 ...
Even so, it still achieved a ballistic coefficient of only 0.153, which reflects very poor long range capabilities; the .44 Henry is a large and slow bullet, giving poor external ballistics and a great deal of ballistic drop during its trajectory, making hitting a target past 200 yards almost impossible for the average shooter.

Ballistic tables for the S Patrone and the s.S. Patrone fired from a 600 mm (23.6 in) barrel. [7] [23] Germany produced many military versions of the cartridge, and continued the development of different variations until the end of World War II. The bullet lengths substantially varied between the different cartridge types, but all were loaded ...
