I'm with HM, whodat. I'd leave him be. that gives the buck character.
One mistake I made and I wish I hadn't.... The only mount I have (so far) I shot him in the lower neck. The taxidermist told me that the hole would always show unless he used an alternative cape. Well being uninformed, I allowed him to put my antlers on a new cape. Which is fine, but each time I look at my mount, I wish I had left the cape just the way it was with the hole so that I could tell everyone that's where I shot him. Now, granted, it wasn't the best shot, but it got the job done and it would go along with the story. ya know?
nice buck your son shot! awesome!
