How much does/did he weigh

[Skyvalhunter]

That's a big old boy with that roman nose. Its so hard to truly judge an animals weight when rutted up like that. Ends up being a guesstimate. He certainly looks like he's been eating well.

unless we are talking about bears. Then they're all 400lb

Use the following chart for what may be a better idea, in the absence of a scale.  It is for whitetailed deer, but should do OK for mule deer.  Measure the chest girth behind the front legs, and find the appropriate row in the chart.  I did a little digging in the literature, and it seems that girth-weight regression models, like the one used to make this chart, explain a reasonable amount of the variation in weight (meaning, the model has a good "fit" or predictive ability).  Sorry for talking stats this early in the morning.  At any rate, here is the link:

If you want to do some slightly more complex math, here is Fig. 2 from Parker (1987), which is on mule deer and elk from Washington State.  Looks like a pretty strong relationship (there is one major issue), based on their sample, and that elk seem to just continue the same relationship as shown by mulies.

I'd guess 275lbs +.  Factoring in that you could drag him 6-12 inch spurts. How much do you weigh? Height? Pretty strong in regards to your age/build? Thats a big boy!  Nice job

Years ago a a sporting goods store in Salt Lake had a heaviest deer contest in addition to their widest rack contest. My brother shot the biggest deer, by far, that any of us had ever taken. Not being aware of the contest he field dressed the deer and took off the legs. When we got it home a friend told us of the  contest and he took it in. Weighed 257 lbs, but he only took 2nd place to a deer that had been dressed but still had legs on.  It weighed 260. They had many deer weighed during the contest, with most coming in under 200 lbs.  I mention this just as a perspective of deer weights. The widest rack that year was 41", but the deer didn't place in the weight contest. I think finding a deer over 300 lbs is comparable to finding one with a 36" spread.

A 300 pound Muley is a big ole buck.   There aren’t many out there.   I saw a great analogy in the other thread.   Something like a 400 pounder being liked to a 30 pound steelhead.

Wow, I bet he weighed a lot! You can tell he is big even without something to reference size in the full body photos

[Rainier10]

This is the biggest body deer I’ve ever shot. I wish I could have got him out whole to weigh him but he was just too big to budge. We deboned him right there.

I have no idea on total live weight but that neck is probably 25 to 30 lbs by itself.  If I had to take a guess I would say that is a 350 lb deer on the hoof.   

    And wow look at that neck! If I just focus on the body reminds me of a graboid from Tremors!

[Wanttohuntmore]

Was this deer shot relatively close to AG land? 

[Widgeondeke]

my only input is with a side of sarcasm.

Live weight = A   
Dead weight = B   
weight lost (C)  =  -0.5lbs   

That is a great buck!  Congrats

Pretty impossible to tell from a pic. Ive only actually weighted game bags and i could count on one hand how many times I've even done that.  Pretty standard and pretty accurate ratio is meat yield is 1/3 of live weight. So if you weigh boned out meat you can get a pretty good idea.

Whats the circumference on that freakin neck?!!!

That's as close as you are going to get.  I've only checked the meat yield vs chest circumference on one deer, and didn't get a scale weight but: chest circumference prediction was 240 lbs live, yielded 87 lbs.  My highest meat yield ever was 92 lbs, but that was a definitely smaller framed buck but had unusually heavy musculature.  A friend got a tank mule deer buck out whole and it scaled 212 lbs hanging dressed weight, and was likely an honest 300 lbs live weight.  300 lb bucks are very large deer!

 Here is a little guy from a few years back.

Here is a little guy from a few years back.

That buck looks to be almost twice the size of the doe!  Hope she can handle him 

[dilleytech]

Idk what that deer weighs but I know you didn’t get 250# of meat off it  awesome buck!
