I guess it depends where you are but in australia they are much bigger than a muley. The average for a male is around 350kgs so a bit over 750lbs but as muleyhunter said big boys get over the 500kg mark so up around 1200lbs.

On dark a mature sambar can look like an angus cow in body size. They are technically classed as the 3rd biggest deer in the world behind elk and moose, followed by red deer at number four.
