Shell id 75mm?

Hello good night,help me with the identification of Shell.

(From evo7125
Looking at the height measurements in the video, the shell seems to be a 75mm. It is a High Explosive (HE) shell, you can tell by how thick the steel is in the pictures.

The black powder in the glass jar, is that the explosives you got out of the shell?
If it is then it could be RDX mixed with aluminium oxide(which is 10x more powerful than TNT).)
