If it has a true taper roll, that should not make the tip end bounce.
If, however, the shaft is warped, that could do it.
Sight down the shaft like a rifle.
All will be revealed.

Not a fan of rolling a cue to check for straightness, heh?
I agree, it's not the best method, but can be used for a quick determination of sorts.
In this particular case, the jnt. faces are suspect.
Connect the shaft & tighten. Roll the cue. It wobbles.
OK, now loosen the shaft about an 1/8 of a turn and roll it again.
If the wobble has now disappeared, it's likely that the jnt. needs faced.
People are very quick to think their pin is bent. Why, I don't know.
999 times out of 1,000 it's not the pin.
Try bending a 3" long pc of 5/16 or 3/8 stainless steel threaded rod and tell us how you make out.
You ain't going to do it by hand.
As to the pin bottoming-out and not allowing the faces to properly mate,
what CM drills the hole in the shaft the exact same depth as the length of the exposed pin?
"Oh, I'm trying to be more perfect than everyone else". Really???
And you never thought that at some point in the future, your perfect cue wouldn't need facings???
The cue in question, in this thread anyway, sounds as though the faces aren't true to one another.
A very light cut of the faces, usually .001" or less will remedy the flopping-fish syndrome.
If the cue is inspected properly, you may have to cut only one face.
