Rifle torque??

Muleman,
Torque is ALWAYS the opposite of the direction of the object that is turning. A right hand rifling twist will rotate the gun to the left, and vice versa.
An engine, for example, runs in a clockwise direction, whenever you change the speed of the crankshaft (rpm) the body/chassis of the vehicle will rotate in a counter-clockwise direction.
Another example is an electric drill, when the bit bites, it rotates in the opposite direction of rotation.
Cheers.

I have this debate with intelligent people all the time. It's not complicated.
right hand twist
the bullet spins clockwise
rifle spins the opposite direction, counter clockwise
It's that simple.
If you can prove otherwise you need to be nominated for a Nobel Peace prize in physics.

Great examples ,I can see what you are saying. So if the fan flew off you best not be standing to the right of it...lol
Why??
Running high scope mounts would enhance torque, not reduce it. The more weight from the centre of the reciprocating assembly imparts increased torque.
I build engines, the larger the counterweights and, where they are from the centre of the crankshaft increases torque forces.
The other factor with high scope mounts is reduction in ckeekweld, which is detrimental to CONSISTENT shot to shot uniformity.
Cheers.
As an engine builder does a lighter flywheel allow an engine to spin up faster?
If your answer is no then you need to revisit some basic physics lessons.
If the scope was mounted lower the angular momentum is going to be less. The torque impulse of the rifle has less resistance the lower the scope is mounted. Hence better control of the twisting effect the higher the scope is mounted.
Yes, cheek weld is an issue if the stock cannot accomodate high mounts. I shoot free recoil so not an issue.
Weight added to the outside of a flywheel DOES NOT increase the torque output of an engine. It WILL increase rotational inertia which effectively resists changes in rotational speed.

Macropod,
You need to re-read my post, I never said adding weight to a crank increased or changed torque OUTPUT. I said it changes reciprocating MASS, which are torque FORCES, not torque output.
Also, if a lighter flywheel allows an engine to speed up faster, it also has an unwanted effect where the engine also falls off speed just as rapidly.
This is why we use zero balanced flywheels and internally balanced cranks on V8’s, it helps hold revs, the internal balancing with lightened pistons, rods and valve train is where the speed increases are made. The flywheel has little to do with the entire package.
I will also guarantee that an UNSCOPED rifle will torque MORE than one with a scope.
Try firing a 505 Gibbs with a 1/10” twist and a 600gr bullet UNSCOPED.

Yep, that's right. And then has the torque impulse attenuated with the scope fitted by the same reasoning. The higher and heavier the scope is mounted above the bore centerline the greater the attenuation of the torque impulse on firing. I don't understand your original response in which you seem to think it increases the torque impulse on firing..

The basic relationship between the moment of inertia and the angular acceleration is that the larger the moment of inertia, the smaller the angular acceleration. The moment of inertia depends not only on the mass of an object, but also on its distribution of mass relative to the axis around which it rotates.
The higher the scope is mounted the lower the moment of inertia/ torque
The lower the scope is mounted the higher the moment of inertia/torque
Mass being equal, distribution around the axis being unequal= unequal torque
physics 101

I think you may have misconstrued this statement, a fluted barrel is just as stiff as the barrel is when it had no flutes and is lighter to boot.
Cheers.
How? I would like to know why. Lighter, yes - stiffer...?
That, by itself, is not true.
Again, I NEVER said STIFFER!!
People like you that twist what is actually said to make an argument piss me off.
You are now the first person to go on my ignore list.
I sure would like to see you at a rifle range, maybe you shoot F-Class with your STIFFER barrel.
I know what’s STIFF, the thing in your hand you keep jerking.
No need to be nasty. I guess my wording was confusing. Stiff, stiffer, stiffy whatever..
Still wondering how the same barrel can be just as stiff after the flutes are cut into the said barrel. I can see that yes, it will be lighter with the barrel steel removed after machining.
Must be magic.
Yes, I do like a "stiff" barrel! 33" long and 1 and 1/4" in diameter.

Must be something about the water spinning in the opposite direction in the toilet bowl.

Here's my input. 28" bull barrel 22 Nosler, 1:7, 88gr@ 2900, F-open. Moment of inertia of wide bipod helps with torque. Still get a little lift on the right leg.
I even have a little weight margin left. Maybe some lead added to right end of bipod.
The next one I make (they are cheap ) might be offset a little.
