Can anyone identify this casing please ?
It was excavated in Lithuania this summer.

Looks like USA manufacture for Russia. What are the case dimensions?

Yes , for me too . Rim diameter is about 90 mm , unfortunately , I can measure accurately only tomorrow . Only lower part is remaining after explosion ...

90 mm is typical for the 76.2x385 case, one of the most common.
