My longest was 378 yards shooting a Ruger m77 .243 with Bushnell 3200 3-9x50, 80 gr Nosler BT and 200 yards zero.. My dad is a cattle farmer so I watch over them pretty close in the spring when they are calving. About 7-8 seasons ago my wife and I were feeding while my folks were on vacation. As we are finishing up my oldest son (7 or8 at the time) says "Look at that coyote!" I look over my shoulder, nothing, so I go back to locking the gate. Then again he says "Right there!, LOOK!!" Again I don't see him, then my wife says "On the other side of the pond, what's that?" Sure enough it a coyote. I grab the rifle out of the truck and lay across the hood. I said "Dang I wonder how far that is?" Looking through the scope the whole time, then I hear her voice, "378". The coyote was sitting looking right at us. So I held on his nose and touched one off, BOOM, flop, center mass, dead coyote. My son was ecstatic to say the least. I'll never forget that day, one of my proudest moments in the woods and I got to enjoy it with my wife and son.
