Far from my heaviest, but only pic of a packout i have on this phone, little over half of a big body muley. Maybe only a mile an a half. My heaviest and longest was probably my last spike bull, 2 hindquarters, the head, and the bag of scrap meat, 5.5 miles back to the truck. Didnt think i was gonna survive that one, but once it was on my back i knew i couldnt take it off till camp.
