Those elk are in much better shape and don't get run around all year long. They have more energy to grow big racks. We hunted them some years ago and they are truly so big that they appear closer than reality. We didn't scale ours but I remember another guy got a 4 point that hung 525#.
Sadly I also remember the WDFW rounding them up in a corral they erected and ended up killing some. Odd how things die when the pros@WDFW get involved. The Indians got the animals.
