The 6.5 Grendel is in the class of .257 Roberts, 30-30 Winchester and outshines the 6.8 SPC in killing potential. It also beats the 100 gr CoreLokt load for the .243 Winchester at all ranges. The only cartridge in this lineup that satisfies the Hornady HITS criteria beyond 600 yards is the Grendel. The others lose out a couple of hundred yards closer in.
Interestingly, the 30-30 has better killing potential at longer ranges than the .243 Win, but the rainbow trajectory makings hitting more of a challenge.
All this on an AR frame.

You've handicapped the .243 by running a corelokt. A .243 running a 105gr hunting VLD @ 3100fps bullet absolutely stomps all the cartridges listed above including the grendel at every range past 200yds, even if you managed to get the 100gr 6.5 bullet at 3000fps. The grendel doesn't hold a candle to a .243 for long range or energy downrange. Where do you get that a 30-30 has better killing potential at long range? Even if a .30-30 were capable of launching a 175gr bullet at 2600fps the .243 still retains more velocity and energy downrange.
