Remember bullet mfgs design their bullets for specific velocity windows. 300 Win Mag bullets are designed for that expected velocity. 9mm Luger bullets likewise. Jacket bonding/locking/design are very different caliber to caliber.
That is true, but the difference in speed for 9mm in a 4" barrel and a 16" is not enough to make a difference. Usually around 100-300 feet per second. Not enough difference to cause jacket separation.

Additionally, I have used 9mm bullets to reload . 357 during shortages. (With a roll crimp). Nothing bad happened.
