Welcome!
A Grendel is a low velocity cartridge in todays terms. You ought to be able to match a 168 Match King .308 load at 600 if you use a 123 Match King or similar match bullet at about 2650 or so. At least in terms of your having to dope winds.
A 6mm CM, BR, PRC, etc will outperform a Grendel at 600. Same with any of the 6.5 cartridges that take more powder. Higher velocities, bullets with higher BC's. That assumes the rifles and shooters are equal. Less recoil with the 6mm's but poor barrel life. Your Grendel ought to go real well to 5 or 6K rounds. No way one of the 6mm's and slightly less of the bigger 6.5 cartridges.
Problem is the 6mms are really single use in these terms. Great for punching holes in paper and hitting steel but thats about it. Your Grendel will do a whole lot more, and do them better, but dealing with winds at long distances isn't one of them. A great universal cartridge for an AR-15 though. It fits almost any need which is really remarkable.
