$40 per bullet. Too much?

they probably have more stringent QA. years ago i was talking to a gun hobbyist and he said most ammo is checked every 10000 rounds or so. expensive ammo is every round or every 10 rounds or something like that

 

[Demo24]

I'd like to see what that does to a target!

 

[AstroManLuca]

It costs $400,000 to fire this weapon... for twelve seconds.

When you've got it like that.....:biggrin:

Needs some high speed camera footage of it hitting something

$40 a cartridge. I believe the bullets cost less than that. Still a crazy rifle to shoot.

Agree but haven't found anything yet.

How is the bullets torque measured?

 

[dud]

I would have thought that the barrel would have been longer than it actually is for such a large caliber. It reminds me of those pre WW II anti-tank rifles.

What's up with the guy saying "lock it slowly"? Is he concerned with the round going off prematurely? Must be a very sensitive firing pin.

I thought the Mosin had a kick ...

It's a measure of force. F=MA

ftlbs?

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

BFG indeed!

What torque? Torque is turning force.

foot-pounds is energy, not force. In other contexts, it can be a unit of torque.

 

[overst33r]

Force != ftlbs

ftlbs?

Thank you.

I was simply looking at 25,400ftlbs mentioned in the OP, which is a torque.

Thank you.

No it isn't.

 

[JTsyo]

ftlbs?

Why not just use KE?

KE=(1/2)*m*v^2

oh it is KE. They are just dividing by 64 instead of 2 because of the 32.2 for lb to slugs.

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.

I see. Thank you.
