Opening Day, I prolly wouldn't let an arrow fly on him.

Maybe hold out for something like him but with the Horns Curling in, that heart shape, that might give him maybe 14-15 and hope I don't regret it--------->

Great pictures Paul! Thanks for putting them up!

That buck will still put on some more horn growth yet before the season. He looks to be about 14" now and may gain a little there but will mostly gain mass below the prong.

Definitely a P&Y buck. In most units, and unless you have shot a bunch of them with your bow and looking for a really big buck, this one's a shooter!

Should be good horn growth on the speed goats this year with all the moisture! Should be some great ones taken this year! Good luck to the guys with tags!

Pronghorns are such cool critters, there's so many unique facts about them! They truly are the quintessential animal of the American plains. When I see a pronghorn I immediately think of wide open spaces, big blue skies, and vistas that stretch to the horizon.

From: njbuck

He looks like a good one to me. Can you guys give some more insight into how to field judge them specifically regarding what I am looking for in an animal that will qualify for P&Y? I have taken one in the past that didn't make it and am looking to make book this time.

T-roy,

There are a lot of theories out there around antelope horn growth in dry versus wet years. The one that makes the most sense to me is that bucks born on a wet year will typically be healthier and produce better horn growth throughout their life time. Most years in antelope country are dry so if you go look back 4 or 5 years from this year and it was wet, there is a better chance for more of those mature bucks to have bigger horns.

A new state record antelope (rifle) was shot in Colorado last year in a bad drought year in a unit not typically known to produce big antelope. Hard to say what circumstances allowed him to grow that big. Crazy thing was that the guy was from out of state and had never hunted the unit nor knew much about it. He even missed the opening weekend and had to take the "leavings". You just never know...

From: StickFlicker
28-Jun-19
t-roy,

I'm one of those that believe the pronghorn have better horns in dry years, at least where I've hunted them. I think it's because their diet might be different in dry years. The plants that grow tall and thrive in wet years might not be as nutritious toward horn grown as the plants they must eat during dry years.

njbuck,

Mass is everything on antelope score. 10 of the 12 measurements have a mass component to them (even prong length since it's measured from the back of the horn), so that is far more important than horn length.

From: Heat
28-Jun-19
Twice as long as the ear is a good reference in the field. So is the eye. Lower mass should be twice as big as the eye is wide. If the buck has upper mass and prongs that make you say "dang" out loud or something similar, well then you probably got a decent one.

From: Ambush
28-Jun-19
Good info for NEXT time! I'm the guy that panicked and sent the arrow without waiting for a side view. I'm going to bookmark this thread, might draw again next year.

From: Franklin
28-Jun-19
IMO.....public land...shoot, private land....pass. I look for cutters to be above the ears....horn mass larger than ear base and total horn length 2 to 2x the ear length.

Watch for deep hooks....the classic heart shape from the front. A massy, lower cutter longer horn is also a very desirable animal. Similar to the OP pic.

Always good advice to see every angle/side if possible. When this guy came in first thing opening morning several years ago, my first thought was to shoot. But when he turned, I changed my mind. Not enough mass above the prong, and I just didn't like the bent back look above the prong which wasn't obvious from the front.

Good pics that show how hard it can be to judge them looking straight at you. When the horns curl back instead of in, you need that broadside look to judge the length. Here is a link to a study on horn growth: https://www.academia.edu/1969440/Factors_affecting_variation_in_pronghorn_horn_growth

Read pages 77-79. Maybe the dry years are not as cold, seems temp in winter may be a contributing factor with nutrition.

From what I've seen in Wyo.....Treeline is right on in regard to his comment that bucks born in a wet year will typically be healthier and produce better horn growth throughout their life time. I've heard this same thing from a well known world class antelope guide.

The circumference of the horn sheath of bucks born in a wet year are larger than if the same buck was born in a dry year. That same buck will have heavier horns for his lifetime. This is a refection of the doe that was healthier and the buck fawn developed and grew better in a wetter year. Obviously moisture plus winter conditions both contribute to healthier does/fawns.

I've kept tabs on current and historic weather conditions in Wyo the past 15+ years and have gotten to the point where I can pretty much predict if many B&C bucks will be produced in any given year in a particular area.

What's amazing about antelope is it's possible to produce B&C bucks at only 3 1/2 years of age. It may take 7+ years for muley bucks and 9+ for elk to grow B&C antlers! Obviously if there is severe drought or winterkill in back to back years there will likely be fewer booner bucks available for a few years.

As mentioned above, mass is the highest proportion of an antelope buck's score. In fact, when field judging the first thing I look at is mass. If a buck doesn't have mass all the way to the tips it likely won't score very well. Prongs and length add to the score.

I've never really gotten too terribly excited about P&Y, Just about any 12 to 13" buck will likely make P&Y. I certainly wish P&Y would raise their standards! With that said, if you harvest a B&C antelope in Colo you have really accomplished something special! If you take a look at the B&C books there are very few book bucks harvested in Colo. In fact, some Colo counties may not even have 1 listing!

I harvested my 2nd best scoring B&C buck in a year that had historic drought. 4 to 5 years prior to that time was perfect conditions. That particular buck was born in a year with excellent moisture. There was a stretch of around 4 years when B&C bucks in Wyo were almost non-existent. This was after 3 years of super drought. All of a sudden after several wet years B&C bucks started appearing once again in that part of Wyo. I burned a bunch of pts on a premium Wyo unit a year with incredible moisture but following 3 drought years. I thought with great spring moisture horns would be impressive....and was super disappointed. I harvested a nice buck but it took lots of time! That hunt raised a giant flag which raised my curiosity. That's when I asked a couple antelope geru's what exactly was going on! From that moment on I've kept tabs on drought plus moisture years in the areas I hunt.

Anyway, that may be WAY more than anyone cares to know...but I thought I would add a few comments. As you can tell I love hunting trophy antelope!

Pronghorn horn growth VS Mule deer, elk, moose antler growth? Might there be a difference and factors that effect their growth and size during dry or moist years. And what about Pronghorn species VS the Deer family and the effects of their over all genetic makeup on horn growth VS antler growth? I do not have those answers.

Genetics, food, water and age...

Less stress (weather, predators or human induced) helps game animals access favorable habitats for better grazing/browsing.

From: Jims

Paul, nice pics! I would say the big difference between deer and elk vs antelope is antelope horn growth is close to 90% complete by July 1 while deer and elk antlers still have significant growth in July and some into August. Most muledeer bucks and elk bulls still have quite a bit of antler growth and development in July and into early August? With that said, late winter/early spring conditions in any given year likely affect that year's antler growth in deer/elk more than that particular year's horn growth in antelope.

Ambush he makes p-y I think 70 or so...p-y is just too low for Pronghorns ....Jim s now isn't that interesting about the buck fawn year being a major factor??? I heard it straight from the Grimmits mouth about a drought year bringing bigger bucks...said no doubt about it...... Jims....I drew a smoking tag in NM this year 36-37....so it be a boon or bust years for the big-uns???

From: Jims
01-Jul-19
NM may be a little different than Wyo. I don't claim to have much experience with NM pronghorn but would think horn growth in NM depends a lot on the previous year's overall precip, precip timing (for vegetation growth) and what the conditions were like 3+ years ago when mature bucks were born in the particular unit you are hunting. I doubt if NM has much winterkill so that may not be as much of a factor. I would think NM horn growth is based a lot more on drought than winter severity like Wyo? In Wyo both factors play a key role. As mentioned by Treeline there are a number of factors for producing B&C bucks....and weather is just one of them!

Another interesting tidbit is mtn goat horns reach roughly 85% of their horn length the first 3 1/2 years of a billie's life. In fact, I know of an Alaska billy that was only 3 1/2 years old and easily made B&C. The guys at the AG&F office where it was checked in were amazed that such a young billy could score so well....and wondered what the billy would have scored if he was a year or 2 older! In Colo it's not uncommon for 3 1/2 year old billies to have 9" horns....and there aren't many older aged Colo billies harvested with horns much longer than 9 3/8" long. Most Colo billies reach close to peak body size at around 5 1/2 years age. There is often a large body size difference between 3 1/2 and 5 1/2 year old billies. I really haven't noticed a whole lot of body size differences between 3 1/2 year old and super old antelope bucks (can get a quick age estimate by teeth).

Another example of horn growth on another species is sheep. Bighorn and dall sheep horns take more years to reach close to peak growth than antelope or mtn goats. The distance between growth rings on rams are pretty substantial the first 6 years and the gap is smaller after 6 years of age. Genetics plays a major role in sheep because you'll likely see different horn confirmation in different herds. Colo is a great example of this. If you take a look at ram horns harvested in S9 they are totally different than horns harvested in S34. In Alaska, most dall sheep horns in the Chugach look totally different than horns in the Delta unit. One of the parameters in Alaska is 8 rings to be legal in most dall sheep units. Dall sheep ring gaps tend to get pretty tight after 8 years of age.

Anyway, this is an interesting post that usually isn't discussed much in detail.....but is fun stuff if you like learning about wild critters! You can tell I get pretty excited about horned game! Adventurewriter, I hope you have a great NM hunt and get a whopper!
