What is the average size of a buck? My friend has shot two nice bucks in the past couple years. The first weighed in at 305 pounds field dressed with several witnesses at the check station. The deer he shot this year weighed around 260-270 pounds. Looking at different wieghts that people post for their bucks it isnt even close. Most are usually around 180- 200 pounds. Could it be because of different food sources or are the deer around here just huge.
