A 300 pound Muley is a big ole buck. There aren’t many out there. I saw a great analogy in the other thread. Something like a 400 pounder being liked to a 30 pound steelhead.
A friend of ours has a pic of a family member with a gigantic mule deer buck from the 20s or 30s that weighed like 450 lbs, it was HUGE!! I can’t remember if it was taken in Wa or Nevada, also back in the 80s my neighbor shot a 5x5 muley that he shot up in the wilderness area by Snoqualmie it weighed 242lbs gutted with no head, no legs, huge black horned buck
