.50 Beowulf necked down to 6.5?

[Sticks]

Thank you all for the input.

This has just been something I have been pondering for a few weeks given all the thoughts on necking down the Grendel cartridge to a smaller pill, I was thinking the other direction, neck a larger case down to a 6.5 since the amount of powder to push the heavier pills seems to be the challenge given the length taking up case capacity. It would be nice to push a 130 or 140 at 2700 in an AR15 frame or mini action.
