Skill, maybe? 533 yards with a 1:9 twist, 20” barrel and 70 grain round with an optic is not that hard. The round doesn’t come subsonic and begin to destabilize until about 575-600ish yards.
Skill, yes. Like I said, and per other posts, it’s doable. The majority of people are not going to be remotely accurate at that range though. The best they can hope for is making a mess, not “hunting”.
