those dead coyote loads are great but I cant always get them so I use 3 1/2" kent fast steel or fiocchi speed steel #2's or BB steel shot loads they have light payloads with some super speed the kent loads push 1 3/8 oz at 1460 fps and the fiocchis push a 1 1/4 oz at 1550 fps. I prefer steel over lead because it doesnt deform and penetrates deeper than lead shot also the 2's or bb's leave nice little holes that usually dont need patching if you keep the hides.

When I yote hunt I prefer to have myself and second person one shooter and one caller. The shooter will have a rifle and the caller gets the shotgun. I would seriously refrain from using a 22 rimfire if you do use a 22 mag at the least and keep your shots short. I use a .223 it with a good bullet like a V-max the yotes dont go far if not drop in their tracks.

I used to use a 6mm but that gun is gone.. long story I posted about a while back. but the 6mm was a little tomuch gun if ya keep hides, Id use a medium size game bullet like the sierra 85 grain gameking the light varmint bullets would leave too big of an exit hole. but the medium game bullets wouldnt expand like a varmint bullet usually leaving an exit hole not much bigger than a grape.
