While in college I worked for the Maine Dept. of Inland Fisheries and Wildlife taking weights, antler measuresments, and tooth samples of bucks shot in northern Aroostook County. In those 2 years I weighted a lot of deer and the biggest I saw (weight wise) was 265 dressed followed by a 264. In my humble opinion, it takes a big deer to dress at over 200 pounds and a huge one to get over 250.
The biggest deflator of egos is a certifed scale. The sad part was hunters who were tickled pink with a deer they thought would dress at over 200 pounds were pissed that it "only" dressed at 185. Still a great deer no matter what.
