A fellow at the range yesterday said the Hornady ELD series don't stabilize until after 300 yards.

Is that true or simply dependent upon using the correct rifle twist?
 
A bullet is either stable, or it's not.

Ballistic Coeffiecient (BC) really doesn't start to show effect until 300-400 yards.

Buddy gave me some 25 caliber 131gr Blackjacks to try.
I informed him my twist rate wasn't fast enough to stabilize them.
Was told shoot them anyways & see.
Yup, keyholed at 100 yards.
Going further wasn't going to suddenly improve that.
 
Cdoc42,

I think your friend confused stability with the distance needed to dampen initial yawing. That yawing is not instability or it would not be recovered from in the end.
 
The point is that if a bullet settles out its initial yawing and flies true, it was stable from the muzzle. That means it was spinning fast enough to settle out yawing motion eventuality. An unstable bullet can't do that. In an unstable bullet's flight, the yawing grows rather than shrinks, and does so until the bullet goes sideways into a tumble.
