9mmLuger-Israeli Dummies

I have what I thought are 4 Israeli 9mm cartridges but now I don’t know. The h/s are as follows
5-73 ח צ, no primer & no flash hole
6-73 ח צ, no primer & no flash hole
9-73 ח צ, no primer & no flash hole
11-73 ח צ, no primer & no flash hole,
The 2 differences from standard cartridges are that there is no extractor groove and the case is .025 longer than a standard case. Are these 9mm Luger or something different.
Thank You Carolyn

Carolyn, these are believed to be dummies for testing packing machines and they are also found with IMI headstamps.

Carolyn, Fede is correct as usual! These are quite good items. Congratulations!

Has anyone seen these in any sort of packing? All the ones I have seen were just loose.
