* The specific cartridge: There are many different .50 caliber cartridges, each with its own unique ballistics. Some common ones include:
* .50 BMG: (12.7x99mm NATO) This is the most common .50 caliber cartridge and has a muzzle velocity of around 2,800-3,000 feet per second (fps) depending on the load and barrel length.
* .50 AE: (12.7x33mm) This is a pistol cartridge with a much lower muzzle velocity, typically around 1,500-1,700 fps.
* .50 Beowulf: (12.7x40mm) This is a rifle cartridge with a muzzle velocity of around 2,100-2,300 fps.
* The barrel length: A longer barrel will generally result in higher velocity due to more time for the expanding gases to accelerate the bullet.
* The type of bullet: The weight and shape of the bullet will also affect its velocity.
Therefore, to get a specific answer, you need to provide more information about the cartridge, the barrel length, and the type of bullet.
