Unidentified Studded Projectile

[oktato]

Hi,
Can anyone help me with identification of this studded shell?
It is approx. 9cm in diameter, including the studs, and 16cm from top to bottom.
The only markings are "M7" stamped on 2 of the studs.
If anyone can help, I would love to know the nationality, period of use and the weapon it was used with.
Thanks in anticipation!
Gary
