6.8 Grendle close to .35 Whelen? I'd say no.
A .267 caliber bullet as compared to a .358 caliber bullet. Probably not .
.35 Whelen cartridge is built on a .30-'06 shell case with expanded neck.
Don't know for sure but I'm guessing the 6.8 Grendel cartridge would be based on necked-down .308 case at the best...maybe even 5.56 case.
I know nothing of the new cartridges.
