What is the best of the AR-15 compatible cartridges for varmints and your optimal barrel length?

Which of these do you already own? And why?

huge fanboy for the 22 ARC after the last year of shooting it at everything from rock chucks and prairie dogs, to coyotes, up through whitetail. currently running the factory 62 gr eld vt in a 16 inch rig for coyotes, and shot a 77 tmk handload at a big whitetail, both have worked famously.

like it enough to build a 16 in howa bolt action as well after ordering a preferred barrel from @herinaz on his website, little more velocity than the ar in a light handy package.

If I was going to build something new for both deer and predator I’d go 6 arc in an AR.

On a side note I wouldn’t build an AR I would run a 18 or 16” built gun in .22 creed.

I'd say that the 22 ARC is probably the best from a pure performance angle, but it is very hard to beat the logistics of a 223 if you plan to shoot it a bunch.
