i have seen 200lb deer before on a deer farm. what people forget is that they bulk on fat during the winter.1lb of fat compared to 1 lb of muscle in mass = the fat takes up 18% more room than muscle does. them deer are mostly fat and then lighter than actually if they was muscle. also have you ever cut up your own deer?one rear quarter does not go 25 lbs alone. its not hard to figure out if you ever butchered your own animals. fat weighs less than muscle. i do believe we have true 200lb deer here in pa. but they are very rare to see. in my time butchering, i have yet to see a 200lb dressed out buck. 195 was the closest and it was a monster that many would guess 300+.
