After you've killed a certain number of animals like deer or elk you start to get a pretty good idea of what they weigh bu if it's something you've never taken before it can be hard to guesstimate what a certain animal weighs.

I've only taken 3 feral hogs so they were hard for me to judge but the guys with me could nail it pretty close as proven by weighing them later at the house. I was off 30-50 lbs.

I killed a really big muley buck once & we had to cut him in half cross ways to get him loaded on the horses. After cutting the head & neck off I took just the front half to a butcher shop to be made into jerky & salami. That front half weighed 80 lbs.
