Please Help German projectile identification

[condor]

Im trying to identify this projectile. I have included pictures of the casing it was in.

 

[HAZORD]

Looks like a canister projectile, typically full of balls.

 

[MINENAZ16]

Belgian used the same canister shot ("boîte à balles pour canon de 5.7cm") but with another case (as far as I'm aware 57x224R).
Ww1 and before. Try to find marking "EP" on the base.
Argentina used also a similar for 61mm Nordenfelt gun (longer shell).
