6.5 grenell vs. 6.8 rem SPC

[meanoldman]

I'm sure this has been beat to death. Can someone point me to some good threads. I have an XCR and would like to get an upper in one of the above but am going back and forth. Best barrel lenght in either-18" heavy? anyone have a good arguement for one over the other?

Thanks,
David

It has been. Use the search function to your advantage.

Spelling it "Grendel" might help.
