aborquez18 has got it 22 long shoot for the head full side shot or strate on. 22 mag you can kill them with side shots.Get a good ammo cci are very good.

As for senses
deer dont have crap on a yote.Yotes have some of the best smell sight and very very good hearing.Best to hunt in a tree stand with 22 or a bow. I have killed lots of yots with my bow only 1 was a drop all the reast ran for quite a ways.

They are a little difrant to call in than deer allso.Yotes like to use heavy trails and fince lines when responding to calls.Dont over call make them look for you with the 22 you will have to have them under 75 yards or so.Find a spot with quite abit of underbrush so he has to keep his head down and cant look up much.In open spots you will most likly get peged befor you get to shoot.

good luck my boy loves to go calling :}
