Are you looking for an all around gun? if so a .270 will kill a coon, possum, coyote, prairie dogs, gofers, bobcats, deer, fox,ect.. but it might be a little overkill for a squirrel or rabbit.Im not saying the .204 is a bad gun, its just i have never heard anyone talk about it. If your a real good shot, you could go cheap and get a .17 caliber, just make sure you remember these words LOCATION!!,LOCATION!!,LOCATION!!
