Ellis is a hunter with rifle and shotgun and a good shot with a DR on running feral boars.
He teaches classes at gunsmithing schools and I was invited to sit in a Friday class where he taught not far from my home. The next day, we hunted boars at the Boars Nest in OK. I was standing behind Ellis when the chase dogs drove a boar down a creek bottom and than out to Ellis. Boar dodged to the right as Ellis fired first barrel but the second barrel dumped the boar as it raced by. Quite a show!
