i dont know if i should stick my nose into this.
from what i am seeing from AR,the horns on bucks are biggerbecause buck is living longer.
you are seeing more bucks with bigger racks.
as for their body weight, in wmu2g, NO, THE BUCKS HAVE BIG RACKS WITH MEDIUM BODYS.
years ago when we did kill a big horned buck bodys were huge,i am not seeing that in clinton county anyhow.
all bucks i got from the AR have not been the big bodys of a buck i shot back in 70s with same size rack.
