I have taken about a dozen antelope, and have been trying to harvest a book buck the last couple years. In 2010 I scouted/hunted 9 days in Unit 33 in Nevada and never found the buck I wanted and went home empty handed. I'm hoping we will score on Wyoming tags and this will be the year! :-)
This winter, while reading Mike Eastman's book "Hunting Trophy Antelope" (excellent book) I learned a pretty critical piece and that is that good mass ABOVE the prong is critical. That was totally new to me, and may be the piece I have been missing.
This is what Mike said in his book "Generally on a buck with great mass, those two lower circumferences are going to be in the seven inch range. However, what separates an average buck from a super buck are the two circumference measurements ABOVE THE PRONG. Finding a buck with three to four inch circumferences on those last two measurements will ensure a quality trophy.
Mike lists it in the following priority:
1. Mass both above and below the prong
2. Prong length
3. Horn Length
I would hafta agree :-)
