Impossible to answer without more details. What range? What bullet weight? What barrel length?
No specific formula. MV is the speed that a bullet is moving when it leaves the muzzle of a firearm. It is measured. Variables that affect it include bullet weight, size, powder charge, composition of the bullet, and length of barrel.
Depends on the speed of the bullet, and the length of the barrel. In the case of a .22 rifle, firing a bullet at 1200 feet per second, from a 16 inch barrel, it will take 1/75th of a second for the bullet to leave the barrel.
Too broad a question. Muzzle velocity is determined by the specific cartridge, barrel length, barrel tolerances, etc.
The question is too vague because it depends on several factors such as, gun barrel length, bullet design, bullet weight.
Yes, the velocity of a 22 caliber bullet can change with the length of the barrel. Longer barrels allow for more time for the gunpowder to propel the bullet, resulting in higher velocities. Shorter barrels may not fully burn the gunpowder, leading to lower velocities.
In relation to firearms, it has to do with the rate of rifling in the barrel. Rifling is the spiral grooves that puts a spin on a bullet to increase it's accuracy. "Barrel twist" is the rate of spiraling or inches per turn. That is the length of barrel it takes to spin the bullet a full 360 degrees.
The BULLET drop is the pull of gravity on the bullet as it is shot, resulting in the bullet lowering in altitude over a long distance. This is what long-distance shooters have to account for on their scopes. Different types of bullets with different weights, sizes, and shapes, as well as the barrel length and rifling ratios, affect how much the drop will be.
Impossible to answer without knowing the caliber, bullet weight, barrel length.
Typically between 2600 and 2800 feet per second. Exact speed depends on WHICH bullet, the powder charge, and the length of barrel it is fired from.
Impossible to answer without more info. Must have the bullet weight, barrel length, and muzzle velocity.
A bullet fired from a short barrel has less time to accelerate in the barrel compared to a bullet fired from a long barrel. This results in a lower muzzle velocity and thus less momentum when exiting the short barrel. Additionally, a longer barrel allows for more complete combustion of gunpowder, leading to higher acceleration and momentum.
