Good post, Pro-Line! I'd say 80% of hunters out there really have no clear idea what their quarry actually weighs, or scores when we talk about antlers.

I used to work in a taxidermy shop where we took in a lot of bears. The average hunter (and I mean average, because the extremes were even worse) considered their 175 lb. bears to be 300-pounders. We could lay out a 125 lb. bear and have guys walk in and call it a 300-pounder. Maybe it's not quite so bad with deer, 'cause they aren't scary like bears, but it's close.

(I had a college buddy who came in from antelope hunting reporting that he had killed a 180 lb. dressed weight antelope doe! Wow. The world record antelope buck probably didn't weigh 3/4 of that live.)

Anyhow, to the main question. Here in MT I hunt two subspecies, one western and one eastern. The eastern strain will weigh a little more and have a little more antler size, but the difference isn't great. For western MT, where I've gathered by far the most data:

Bucks
1 1/2 years old75-95 lbs. dressed
2 1/2 years old100-130 lbs. dressed, 75-105 gross antler score
3 1/2 years old 140-170 lbs. dressed, 100-130 gross antler score
4 1/2 and up 170-maybe 240 lbs. dressed, 110+ gross antler score;

Does
All ages 70-110 lbs. dressed, 0 gross antler score (gotcha!).

My bucks (dress weights approximate):
'003 1/2 y.o., 160 lbs. dressed, 111 gross 10-pointer, western MT
'02 3 1/2 y.o., 185 lbs. dressed, 123 gross 8-pointer, eastern MT
'03 3 1/2 y.o., 145 lbs. dressed, 109 gross 9-pointer, western MT
'04 4 1/2 y.o., 195 lbs. dressed, 144 gross 10-pointer, eastern MT
'05 4 1/2 y.o., 185 lbs. dressed, 135 gross 8-pointer, eastern MT
'06 6 1/2 y.o., 170 lbs. dressed, about 110 7-pointer, western MT.

My '03 and '06 bucks were taken at the tail end of the rut, and both bucks probably had lost 10-15% of their body weight.
