Grendel vie six8 recivers

[centerfire]

Did you use the LWRC upper and lower 6.8 receivers or a 6.8 lower and standard upper? My barrel will not accept cartridges seated 2.30", I think I'm only .020 off the lands with 107TMK seated 2.260". This is pretty interesting though, this would allow a throated barrel to run 130gr or 140gr bullets without burying the bullet in the case.
