Quick Answer
To field judge the size of a Coues deer buck, look for a rack with a wide spread, long main beams, and decent points. Measure the main beams against your boot or a branch to estimate their length. Compare the overall rack shape and size to known reference points.
Measuring Main Beams
When measuring main beams, it’s essential to note that those of a large Coues deer buck typically range between 24 and 30 inches in length. Hold your boot against the main beam, and if it’s roughly the same width as the beam, that’s a good indicator of its length. Alternatively, use a branch with a known width as a reference point.
Comparing Overall Rack Size
Measure the spread of the rack by holding your arms apart, palms facing upwards, and estimate the distance between the tips of the antlers. A large Coues deer buck’s rack spread should be at least 22-24 inches wide. The overall rack shape should be symmetrical and have decent points, with a minimum of 4-5 points per side.
Considering Age and Genetics
Keep in mind that younger Coues deer bucks grow in size and antler development over the years. Genetics also play a significant role in determining antler size, so it’s not uncommon to see large bucks with impressive racks. When judging a buck’s size, consider its overall body condition, which should be muscular and well-proportioned to its rack size.
