Pellet exiting muzzle, with formula for energy overlaid.. Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge.
Projectile weight: 3.6 kg; Muzzle velocity: 1800 m/s; Muzzle energy: 5.8 MJ; Penetration: 245 mm at 0° at 2000 m, 140 mm at 60° at 2000 m, (energy at 2000 m is 4.2 MJ)
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 ...
The Taylor KO factor multiplies bullet mass (measured in grains) by muzzle velocity (measured in feet per second) by bullet diameter (measured in inches) and then divides the product by 7,000, converting the value from grains to pounds and giving a numerical value from 0 to ~150 for normal hunting cartridges.
Higher operating pressures of the cartridges like the 9×19mm major and .38 Super are preferred over, for instance, the .45 ACP, since it provides more gases for the compensator, dampening the felt recoil and muzzle rise more. Other handgun divisions are not permitted muzzle brakes, making 9 mm major and .38 Super uncommon outside open and ...
the inherent potential accuracy of the computer program and other firing control components used to calculate the trajectory; The ambient air density is at its maximum at Arctic sea level conditions. Cold gunpowder also produces lower pressures and hence lower muzzle velocities than warm powder. This means that the maximum practical range of ...
Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots or shell) with respect to [1] the muzzle at the moment it leaves the end of a gun's ...
A copper-plated hollow-point loaded in a .44 Magnum, for example, with an original weight of 240 grains (15.55 g) and a diameter of 0.43 inch (11 mm) might mushroom on impact to form a rough circle with a diameter of 0.70 inches (18 mm) and a final weight of 239 grains (15.48 g).
