I agree with Lew Curtis that this is not an original Israeli factory load, but rather a converted cartridge. The semi-truncated projectile has possibly been changed, although I don’t think so. I have a TZ 85 round with the same shape, and the same six nose splits, but the original hollow-point bullet is seated deeper in my round, or a shorter bullet - I believe the former.
If, as I suspect, the bullet is original to the case, it has been removed and converted to the primer activated “explosive” configuration, and then reseated, for some reason not to the original depth.
It is not a CCI bullet, as far as I can tell, although it would not be impossible for IMI to have been using bullets contracted from outside their own company for the original hollow-point loading.
I do not believe that in its current form, with the primer inserted, that it is an original Israeli load. You find these conversions to “specialty” loads all the time, as sometimes surplus ammo is cheaper than surplus ammo on the market, and it pays these small companies making these almost useless explosive, incendiary, etc. “specialty” loads to just convert ordinary hollow-point ball cartridges rather than buy “new” components.
Even Magsafe Company, with their wide line of different, usually shot-filled bullets, converted original bullets in already loaded ammunition, when it saved money to do so.
