seems to me like the colder the environment the heavier they can be, that and age and good food sources
but colder temps, seem to add up extra layers of fat that add Lbs
My heaviest deer have always come from northern Alberta Canada, many were far past the 250 lb mark gutted on a certified scale, they grow em big up there, very impressive to see deer that size and larger!
and just a little tid bit of info on heavy deer
the heaviest whitetail ever killed in Pa as far as I know that was officially weighted, , was a DOE with antlers! and was something like 400+ lbs, I forget exact weight
Maybe OT can recall the details, as it was a while back now!, so a odd ball on a few levels!
