RE: main beam length/Age
actually in my woods the herd is really consistent when talking age/score relationships up to 3.5yrs old. I have taken 14 3.5 yr olds and older and 2 2.5 yr olds......both of the 2.5 yr olds have main beam length of 17 to 19 inches and main beams on the 3.5 yr olds and older that i have taken have all been from 21 inches to 24 inches.
As for body weights the 2.5 yr olds weighed field dresses 155 and 160.....the 3.5 yrs olds weighed in from 165 to 200 lbs
