In my neck of the woods I will say the average 3.5 year old or older will go 180-210.This is mainly farm land with alot of bush.
Its VERY common to see deer tipping the scales in the 230-240 range dressed and some I have personally seen in the 260 lbs rangebiggest being a 10 point going 302.
My personal best was 198# dressed 13 point.He was very stocky,but short in comparrison to the average deer.
