I have hunted big game animals lots, and by lots I would imagine on average 75 days a year for big game. Now out of the species it would be elk, mule deer, antelope, whitetail, moose, black bear and mountain lion. I have hunted all with a bow and rifle. To be honest, I believe hunting a mule deer during archery season is the hardest. I don't care what people think, mule deer are extremely smart! Well atleast until the rut where there manly hood takes in, but still not with all the bucks. During archery, these bucks are usually in big bachelor heards and usually always and I mean always have a buck facing every direction. For the most part they can not be patterned and like to choose several different trails. This is just my opinion. Subject to change someday but for now will stick with muleys as the hardest.
