The snow depth this year appears to be pretty localized from 1 area to the next. The winter hasn't been very bad and this should be an incredible year for horn growth in the particular area I'm hoping to hunt this coming season.
I've been keeping tabs on horn growth in areas I hunt in Wyoming for years. I've actually harvested 2 of my highest scoring B&C bucks the years that had historic droughts. I also saved up a bunch of pref pts and drew a "premier" unit that was re-known for super high scoring Wyo bucks in a year when I thought all the stars were aligning for incredible horn growth. There was fantastic fall through spring moisture after several mild winters. I lost count but conservatively looked over more than 700 different bucks in that premier unit in 4 days. I only found 1 buck that scored 80" and the others were low 70's bucks. I noticed that same year there was hardly 1 buck in Wyo that made the B&C books. What the heck?
It's obviously important having great moisture, nutritious feed, genetics, and a little age on bucks in any particular year. It took me a while to figure out why I harvested giant bucks in historic drought years and looked over hundreds of dink bucks in a prime unit in a wet year following 5 mild winters when the conditions seemed perfect.
After talking things over with a re-known antelope guru he brought to my attention that bucks born in droughty years may be plagued for life with smaller pedicle bases than those born in years with great, timely moisture. If you've had the chance to look over many antelope skulls in different years from across the country you will notice that pedicles vary dramatically. The highest scoring bucks I've harvested generally have the most mass....and this translated to great mass the entire length of the pedicle on the skull. It sure makes a lot of sense when I've aged bucks and related what feed and weather conditions existed the years they were born.
The same antelope guru also mentioned that it generally takes 3+ years to produce a B&C buck. That's WAY shorter time than deer, elk, sheep, and other big game species tend to produce B&C proportions. How does all this relate to your question? You might take a look at the weather and conditions that have existed the previous 3+ years in the unit you intend on hunting. If there were favorable moisture conditions 3+ years ago there's a pretty good chance there will be good horn growth this coming year if those 3+ year old bucks survived winter/hunters! If 3+ years ago was historic drought you may consider holding off using all your pts? Obviously severe winterkill and drought will effect fawn recruitment and the number of bucks that were born and survived through those years.
