RE: Average score
ya hard to say with button bucks, yearlings etc...
better question might be what's your avg 2.5yo, 3.5yo, etc...score...
here where we hunt in IL, a big 2.5yo will go 150" is what i've personally experienced, dad shot a 155" and 151" 2.5yo here, gross score....141 and 146" net..
a 3.5yo can go 180"+, again father shot a 3.5yo 184" gross.
Course these are big for their age, but a 130" 2.5yo is not hard to come by in my own experience. Drive's me crazy have a relative who consistently shoots 2.5yo...130" bucks, which isn't a problem, but the whole idea behind our hunting has been managing for larger deer, and he seems to not be willing to follow the plan. going to have to find my own set up next year I'm thinking.
