MRA Renegade, 6.5 Grendel, and hard extractions

[700-223]

Bump. Anybody found a solution for this yet? Or, conversely does anyone have a MRA renegade in Grendel that is running well without hard extraction?

Lower your load pressures a bunch... use stiffer brass that will not expand at the lower pressure... load a lighter bullet so you can lower pressure and load on system

On the MRA Facebook group, there was at least one fellow who said he had 6.5 Grendel running just fine.

Myself, I gave up. Lighter bullets and polishing the chamber didn't make a difference. So, I put a 6x45 barrel on, and things run just fine.

I’m running factory ammo, haven’t polished the chamber yet but sounds like that’s the last step. 60 or 80 rounds in, no improvement yet. Very disappointing if I can’t get this to work. A 12.5 inch hunting rifle sounds awesome - my 556 upper sounds great, hope something works out.
