All fine choices if ammo availability is not considered. Of those I would go with 6.5 Grendel shooting 120gr Fusion / Gold Dot simply due to range with runner up being the 350 Legend.
Some on this forum have mentioned the 224 predator or arc are solid wildcat offerings and I see that position has a lot of merit; however,
one problem I see with those 224's (other than being a wildcat) is that they don't sell 90 grain fusion / gold dots as components (they have to be acquired from Valkyrie pull-downs).
The reason I like the fusions / gold dots is toughness / expansion and hunting-good BC.
Other than that those 224's look attractive in terms of performance (SD, velocity, energy etc).
