He was dominant and his rack tells me he should be the stud that will not tolerate any competition. Have you seen his antler genes show up in other bucks on the farm. Of course it is likely he runs them off before they get the age for those characteristics to show up.
I killed a KY buck one season with a 3 inch hook off one eye guard - we saw that on one other buck next season. That buck's range was about 25% on the lease and 75% off the lease.
You killed a great buck for sure. Congrats!!!
