Look up Seafire on AR,he has worked a lot with both and has a lot to say. The 6.5x57 is an odd ball 57,more like the 8x57 then the 7x57. The easiest way to get brass is to false shoulder 7x57 and fireform. I think case capacity is a brand question.My 6.5x55 barrel started life as a 6.5x57,just for the ease.
