Sounds about right, I think the 57R case is the most common after the 72R and 74R variants. You should be able to trim 72R brass to 57mm and fire form. I'm not to familiar with the ballistic on the European variant but from the proof marks I believe it calls for a 283 grain bullet at about 1650 fps. Very similar to the .360 2&1/4" NE.
