Nice buck there Joel!
Those Blacktails look like some burly buggers. Are they very heavy? Getting a weight on one of those would be a bit tough I imagine.
I have had a huge number of them on a scale in the round and field dressed. Lots of difference in weights between different areas/habitat types. On Afognak or in PWS in the old growth a yearling buck runs just over 100# field-dressed. A really big buck might go 165 or so.
Out in the open on Kodiak I have seen many bucks in the 200#+ range. Yearlings are about the same as in the old growth. The fat across the rumps on these deer can be unreal.
