You could kill a coyote with a 22 but you better get him in close and hit him in the neck or eye.How about your sks it would make alot better gun for the job and be more likely to kill him fast if you put a scope on it,it would do even better,I have killed a 10pointer years ago with a borrowed SKS and open sights,at about 120yards,that was my first deer,20years ago,the main thing is get out and go hunting,and possibly take a kid they are the future of the hunting sports.
