When you've got it like that.....:biggrin:It costs $400,000 to fire this weapon... for twelve seconds.
I'd like to see what that does to a target!
Agree but haven't found anything yet.Needs some high speed camera footage of it hitting something
How is the bullets torque measured?
ftlbs?How is the bullets torque measured?
he cartridge develops a "muzzle energy" figure, either in joules (metric) or foot-pounds (ft lbs). This is calculated as follows (please note that although the correct term is "mass", I have used "weight" instead for easier comprehension. Mass is a constant regardless of gravitational pull, whereas weight depends on the gravity. However, on the Earth's surface the two are effectively the same):
Joules: multiply the projectile weight in grams by the square of the muzzle velocity in metres per second (m/s), then divide the result by 2,000. So a 40g projectile fired at 800 m/s will generate (40 x 800 x 800)/2,000 = 12,800j
Foot-pounds: multiply the projectile weight in pounds by the square of the muzzle velocity in feet per second (fps), then divide the result by 64. Note that there are 7,000 grains in a pound, so for bullet calculations you can enter the weight in grains then divide the resulting calculation by 7,000.
To convert foot-pounds to joules, multiply by 1.348.
To convert joules to foot-pounds, multiply by 0.742.
15.432 grains = 1 gram, 2.205 pounds = 1 kg and 3.281 feet = 1 metre

It's a measure of force. F=MA

ftlbs?
What torque? Torque is turning force.
Force != ftlbs
Thank you.
I was simply looking at 25,400ftlbs mentioned in the OP, which is a torque.

No, it's a unit of energy in general. Could directly translate into joules. It can be used to measure torque, but that's not the context when it comes to firearms ballistics.
