Great prongs on these mature bucks
You’ve drawn a license for the fastest land animal in North America, the Pronghorn! Well that’s great but how do you know what to look for in a mature buck? The pronghorn is one of the most difficult animals to judge in all North America. I’m speaking in terms of antler size of course! Even after being a professional big game hunting guide in Wyoming for seventeen years I still misjudge pronghorn on the hoof. Now pronghorn are not antelope but are often referred to as such because they closely resemble the true antelope in Africa. So, I will use both terms as I refer to them in this article. We regularly call them “speed goats” as well (because of their similar features to goats and notorious speed).
So why are pronghorn so hard to judge? First, their antlers aren’t very large to begin with. Therefore, a difference of twelve inches and fourteen inches is hardly anything at 800 yards but a world of difference up close. Due to the far distances from which you will be looking at antelope, you’ll need to know what to look for. I’m a firm believer that score means very little and that the trophy is in the eye of the beholder. However, to better help you understand what to look for in the antlers of a mature pronghorn I’ll be talking about SCI scoring a little bit. It’s also a good way to convey relative size to other people. You get one length measurement on each side starting from the base and ending at the tip. Then you divide that number by four to find where you will take your four mass measurements. Finally, you get one prong measurement on each side. (ex. figure below)
Mass is the most important factor when it comes to score. Now, you’ll see in the figure that two mass measurements fall below the prong and two above. If the third mass measurement spot falls below the prong you are getting a much bigger score than if it is above, so keep that in mind. When judging a buck, you’ll be critiquing three main things: mass, length and prong size.
OK, so how does one take this basic knowledge to the field and successfully judge a goat at 1,000 yards!? I’ll give you a couple quick, handy tricks to do so.
Body size can help in some cases when looking at comparable bucks at great distances. Look for a stout block body with a thick neck and a big belly. Sometimes older bucks are lighter in color, but I’ve found that color varies greatly and doesn’t always indicate a bucks age.
So, let’s recap on the three main aspects of the antlers: mass, length and prong size.
Mass is the most important attribute in terms of overall antler size. Look at the eye in respect to the size of the antler from the side. If the antler is as wide as the eye or wider you know you’re looking at some decent mass. Big bucks will have a circumference at the base of 6 inches and more.
2. Length is perhaps the first thing we notice and the most impressive part in the overall “look” of a buck. Some bucks have huge curls that make them look cool (I love the heart-shaped ones). Some bucks don’t curl much which makes them look taller and that can be neat as well. Mature bucks range from 12 inches to 16 inches and up. When looking at a profile view try to estimate how many inches the tip of the antler is above the ear.
3. Prongs are the awesome features that make the pronghorn so unique! They can stick out, go up, go down, curl in, curl out, etc. They usually aren’t more than 5 inches, but some bucks get huge prongs that go 7 inches and over. The prong adds another big contribution to the “overall” look of a buck.
Pronghorn are unique in so many ways and they all differ from one another. The next time you’re out chasing “speed goats” remember the guidelines for field judging them but also remember the true trophy is in the eye of the beholder!
