RE: Antelope Question
Antelope fight fierce battles during the rut in September. Many bucks which are taken have gauges out of their necks from the other bucks horns.
Antelope shed their horns in late October early November. The horn as I understand it is made of a hardened hair like substance which is quickly eaten up by small critters which is why sheds are not normally found from antelope. After they shed there is about a 6" internal base which remains on the buck.
