120 gr bullets stabilize in a 10" twist 260 Rem?

I would rather use the 120 gr Nostler ballistic tip bullets [1.220" long].
I would like to shoot animals out to 500 or 600 yards, and want the bullet to remain stable down to ~ 2000 fps.
This calculator make it look like I am ok.

This calculator makes it look like I am only good down to 2500 fps

And that SG variable.... How would I measure the density of bullets? Drop them in water and weigh the spillage?

Are we a nation of competing ideas, or a nation of forced conformity of thought?
