The table below are examples, and for the same caliber different bullet weights can be used. Bullet velocity depends, along with other factors, on bullet weight, powder types used and barrel length for the particular firearm. Some cartridges not suitable for competition are included for reference.
For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
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 (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
Power factor is calculated by bullet weight multiplied by velocity, divided by 1,000. To qualify for Major power factor in USPSA, the 9mm Major loads must reach higher velocities than standard factory 9mm Luger ammunition, making it suitable for competitive shooting but not readily available as commercial off-the-shelf ammunition.

The ballistic tables are made up for a factitious projectile being defined as: "a factitious weight and with a specific shape and specific dimensions in a ratio of calibers". This simplifies calculation for the ballistic coefficient of a standard model projectile, which could mathematically move through the standard atmosphere with the same ...
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 ...
There is wide variation in commercial ammunition. A 180 gr (12 g) bullet fired from .357 Magnum handgun can achieve a muzzle energy of 580 ft⋅lbf (790 J). A 110 gr (7.1 g) bullet fired from the same gun might only achieve 400 ft⋅lbf (540 J) of muzzle energy, depending upon the manufacturer of the cartridge.
Here is a table comparing rifles based on a maximum ammunition load in box magazines of 10 kg (22 lb). ... Cartridge weight Bullet weight Velocity Energy 5.56mm NATO ...
