My record so far is a coyote from last year, he was walking angled slightly away, I ranged him at 553 yards and settled on the rifle for the shot. I had to deal with about an 8 to 10 mph wind coming from about a 45 degree angle and he was heading into the wind. 243win 55 grain Nosler Ballistic Tip, with just enough lead and holdover, I punched him a little too far back, he did the old death spin and headed for the trees in a swamp area, never found him. Not exactly sure what the actual distance was as he had taken several steps before I could get on the trigger but my guess would be 560'ish or so.
