I hunt them in Arizona where they are considered big game, so all regulation that apply to deer, elk, sheep, and other big game apply. So no feeders and fair chase only. I also use a pistol, granted it is a Thompson Center Contender in 7-30 Waters I have also taken them with a 44 mag, 41 mag, 357 mag, and a 40 S&W.
We find them quite challenging at times, if they wind or spot you you'll be in for a long hike trying to get back onto the herd. We do mostly spot and stalk. We know canyons that they like and a lot about their habits when the weather is bad or windy. After 30 years we still find it fun and enjoyable.
Nice looking mount and congratulations on it.
