A .280 Remington bullet typically travels at a velocity of around 2,700 to 3,000 feet per second (fps), depending on the specific load and bullet type. This speed can vary based on factors such as barrel length and bullet weight. Overall, the .280 caliber is known for its effective performance in hunting and shooting applications.
@ 2000 FPS
280 x 3600/5280 = 190.91 mph
The legal limit is 300 feet per second. Some fields restrict this to 280 or 260 fps.
280 fps
The same as any other 9mm. It can range from 800 FPS to well over 1000 FPS depending on the cartridge.
It can vary from 2000-2800 + FPS
In a snail, YES. In a bullet, NO!
The dry air speed of sound is about 1125 FPS, so anything over that is considered supersonic.
FPS is the measurement of speed in feet per second. Depending on what kind of bullet you are talking about, bullets can travel as fast as 4400 fps. Here are a few examples: 9mm-about 1050 fps. .45ACP-about 900 fps. 5.56mm-about 2700-3300 fps. .50bmg-about 2900 fps.
The EXACT muzzle velocity will vary with the weight of the bullet, and the barrel length of the rifle. The 140 grain bullet is fairly popular, and leaves most hunting rifles at about 3000 feet per second. Lighter bullets may travel at 3300 fps, heavier at about 2700 FPS. IMHO, an excellent long range cartridge.
Depends on the .22 cartridge, what weight bullet, and what it is fired in. Some .22s travel slower than the speed of sound (about 1100 fps) some high velocity 22 LR cartridges fired from a rifle reach muzzle velocity of 1750 fps with a 30 grain bullet. The .22 Magnum may reach 2200 fps with the 30 grain bullet.
That is sort of like asking how many miles per hour does 100 horsepower equal. Ft lbs is energy, and FPS is speed. There IS a formula to calculate the energy (in foot lbs) of a bullet, but to use that, you need to know SPEED in FPS, and WEIGHT (in grains) of the bullet. A 40 grain bullet at 1000 fps is pretty weak. A 400 gr bullet at 1000 fps can drop a moose.
