Go to this site and study the chest measurement chart to get a RUFF Idea of what your deer weighed on the hoof and once field dressed.

then figure the amount of usable meat at the 40% scale if you have it processed and feel grateful you got 40%.
Here our average 1 1/2 year old bucks run about 150 lbs. older does can get close to 180 190 Lbs. I figure average is 150lbs. and spring fawns by our fire arm deer season time run from 75 to 125 lbs depending on birth month. A few even in December in my area still have their spots.
