In the US - in the north - we often talk about Dressed Weight rather than live weight. A good Mature Whitetail buck in the Northeast will dress out at about 200 lbs - with 240 lbs live weight about right. Younger Bucks in the 1.5 - 2.5 Year Old range will be about 120 and 150 lbs dressed, respectably.

Weights vary around the US - and Midwest deer generally can weigh more and Southern deer generally weigh less.
