Tony,
You're spoiling our fun!
Your criteria are part of why Warped is probably right about a military cartridge fitting the AR-15 magazine well will likely be the Grendel. I would go as far as modifying the statement to one based on the Grendel...
A necked-down 6.8 SPC might have some adherents, but the brass is too long for decent 6.5 nose shapes. Maybe 6mm but I'm not so sure about the space there either. Going all the way down to 5.56 is about the best that case might do for getting decent nose shapes and velocity.
Cheers!
Joe
