That's all going to depend on how well that particular rifle shoots. Every rifle is different, even if it's the one directly behind it on the assembly line that is identical.
As for range with that rifle and that scope, I have no idea. I know there's guys shooting the AR's with high-end Grendel uppers upwards of 1,000 yards and hitting steel with no issues. There's some guys shooting beyond that. Not sure I'd recommend that, but some are doing it. But I will say this, ballistically, inside of 500 yards, the 6.5 Grendel should be great for deer and coyotes with no issues.
