Welcome to the Forum Fredo!!
You have been given excellent advice above.
Bullets jumping the crimp are not uncommon in certain situations. Light guns,, combined with heavy recoiling ammo can easily cause this.
In reloading,,, when we are making our own heavy recoiling ammo, we always try to make sure we have a good crimp to help prevent this.
But I've also seen it happen to lighter ammo in brass that has been loaded several times,, where the neck tension isn't very good. More often in a semi-auto rimless such as the .9mm because you can't roll crimp the case. The case headspaces on the mouth,, not the rim. In fact,, in my .9mm revolver,,in USPSA competition,, once I eject a moon clip with live rounds,, I never re-use them in a match. And I also take them & run them back through my press & re-seat the bullets & re-do the taper crimp. BECAUSE I have bullets creeping forward some.
So, as noted above,, switch ammo, and just to be cautious,, shoot one or two, checking the remaining ammo for bullet jump to prevent a round from jamming up the gun again.
