How much horsepower dose a 30-06 generate?

    Using regular, or premium unleaded?

    @ What RPM??????

    Maybe you could get it dyno'd somewhere

    786 give it 300 + - for powder loads & ball weight difference

    For comparison a LR.22 gives 45-56 HP also depends in manufacturer variations.

    Never understood hp -only torque. Maybe someone could check the torque of the spinning bullet as it leaves the muzzle.

    OK guys. You have gotten my interest here. Off the top of my head, I would say that a bullet leaving the muzzle has zero torque. What it has is rotational inertia. As for the HP thing, I'll think about this tomorrow before the Miller Lites!

    Zero torque? Just think of the force needed to stop a bullet from spinning. Torque is twisting power. As for the HP, Torque question, I'm sure they are very high, for a very short time. I think you have to have a sustained source, to have a reliable reading. I'm sure I could look it up, and post figures. I really don't want to take the time too do this, I see no reason for it.

    My friends, you have me at a disdavatage! Permit me ... there is no longer any energy being produced after the bullet leaves the muzzle. There is no torque because there is no input of energy. What we have here is an object spinning with a defined mass. That is rotational inertia. No energy - no torque. More tomorrow on that HP thing!

    FYI: Torque is NOT a degree of twist, it is the strength of a force acting on an object. 1HP was stated by Watt as the amount of energy required to move 33,000Lbs one foot in one minute, or 550Lbs one foot in one second, etc. One Ft-Lb of torque is the same at 5,250rpm. Today we generally measure torque and calculate HP as a mathmatical result of torque acting over time. HP can be increased by increasing torque OR the rate at which torque is applied, or a combination of both.

    For automotive engine applications:
    HP=(TQxRPM)/5252
    TQ=(5252xHP)/RPM
    (Yes, this means that the torque and horsepower curves for ALL engines cross at exactly 5,252rpm)

    To figure out the torque generated by a 30-06, I would guess you would first figure out the amount of inertia resident in the bullet as it leaves the barrel, call it X.
    HP=(Xx1)/5252
    If you are firing semi-auto, you could include a rate of fire variable, call it R
    HP=(XxR)/5252

    I have never done calculations like this before, but I know that the GAU-8 on the A-10 Thunderbolt produces approximately 10,000Lbs of thrust in one second of firing! Oh, and I don't know off-hand how to convert HP into LBs of thrust, but I could probably dig up the formula if someone is dying to know

    If you want a REAL headache, look at this: http://www.racquetresearch.com/torque.htm

    HP is in a very simple term...is how fast an object is moveing and how much weight is moving at that given speed.
    i used to know all these formulas from school "diesel mech" to figure out
    torque and hp from engines to designing hydraulic systems..IE hydraulic motors and cylinders.

    HP=PLAN divided by 33,000 (P-pressure x L-length of stroke x A-area of the piston x N-number of cylinders)

    Geez, I didn't know we had so many rocket scientist here! So, let me get this right, We have 16 horses on the place, i figure there ain't one of them that could move 33,000 pounds one foot in a whole day! So, If I had to use four horses all at the same time to move the 33,000 pounds 1 foot in one minute.... WAIT, I GOT IT!!! Now I know why they call them Quarter Horses, 1/4 HP each!
    LOL!

    Guns-n-painthorses -- an answer like that would get you strung up where I come from! (but I like it!)

    Torque is a force acting at a distance to a point. A bullet is rotating, so it has some torque. How much? Have to dig out a book that's three layers deep, but I do know that if you figure out how fast a bullet is spinning you'll understand why cast bullets don't work in high-velocity rifles.

    Anybody care to guess how fast a bullet spins?

    The easy way to think of the bullet's torque is to ask how much effort would need to be applied to stop the bullet's rotation in flight. Obviously, more than zero.

    Assuming the bullet were a little space capsule, and you could put little retro-rockets on it, how much energy would you have to expend to stop "roll." My guess is not much, less than a single horsepower. I don't think there's enough momentum there laterally that simply stopping the spinning, assuming the bullet continued to travel forward, would be that tough.

    I've got it, lets fire this bullet out of a non rifled
    barrel and get rid of one half of the problem.

    Hhmmmm,

    I wonder if it's safe to DINO test a 30-06?

    Oftimes the question is much more interesting than the answer. Such is the case here.

    To convert from foot pounds per sec to horsepower devide foot pounds by 550.

    Guys, I don't give up easy. What we have here ... is a failure to communicate! I'll try this one more time. Whiteclouder, you are right. The answer isn't interesting because it is zero! Yes, you guys have the correct numbers from the book correct but none of that applies. HP and torque infer that power is being created. Once that bullet leaves the barrel everything slows down. There is no power being created. There is no HP or torque. What you do have is angular and linear energy and momentum. We have a problem with terms here. I remember 40 years ago my physics teacher asking us how much work is being done if we pick up our 200# girl friend off the sofa, carry here 75 feet down the hall, and toss here in a bed at the same elevation as the sofa. The answer is zero. Many of my classmates (that had fat girlfriends) agrued that for a long time. Terms and definations are very important.
