I see no sense in it.
How accurate do you think the repair will be first of all.
Second, I would want the buck to be as he was when taken.
Fighting is the nature of a buck and any broken tines, rubs, gouges and
scars should be represented as they are.
I have a 10 point on my wall right now with three of his points
snapped off and quite a few wounds to his face and neck that show.
That is how he was and always will be.
It's your buck and your choice.
There are those that could do it and make it look real too (But you will know it isn't)
