I wish I had better recommendations for you, but I don't.

Temperature doesn't give you air density.

You need pressure as well.

Yeah, the ballistic coefficient is not strongly related to pitching moment coefficient.

The problem is that you really need the separation between the CG and the center of pressure.

Okay.

Okay.

And that's really related to the mass distribution within the bullet and the length of the bullet.

Now, the length, yeah, the length is in there.

That kind of covers two factors.

That covers the separation between the CG and the CP, and it may cover the transverse inertia some.

Right.

It still doesn't take into account the effect that the shape of the ojibe.

So whether you have a tangent ojibe, a secant ojibe,

a hybrid ogive or a conical ogive on the bullet, all those have, for the given ogive length, they all have a different center of pressure loop.

So it's like, well, okay, if you're not distinguishing amongst the ogive shapes, you don't have a snowball chance in hell of predicting the actual stability of the bullet.

That was done for dispersion purposes.

Okay.

And they, they only, they only fire like light, really light bullets, like 50, 55 grain bullets.

Right.
