.030 over arc

[Tx264]

Have a group buy arc barrel.want to ream case length. 030 longer,leave the bullet where it's at.
Talked to Ray at,Monson, said he could make a reamer that would do just the body and neck.
Resizing new Grendel brass.
No trimming
No bumping shoulder back
More case capacity
70 to 95 gr bullets less jump to lands.
Sound like a good idea?

sounds great. It's what the 6mmARC was should have been.

Sounds to me like you discovered the Rob Whitley 6mmAR.
Pretty much what he describes in his article:
6mmAR -- 6mm Solution for AR-15s (Grendel Brass) (6mmbr.com)

Many men much more knowledgeable than I have gone down this road and I greatly appreciate your input.
Almost went that route 3 years a go.
Reason I didn't
Availability of dies,had to use grr bushing dies or high dollar whidden.
Availability of manufacturer load data.whitleys were way hot, some guys were blowing up guns.ask sh.
Availability of barrels.cra would take a year or more.xcaliber only had h bar or pencil.
