I use a 270 for deer, black bear and coyotes (I'm not saving hides in this communist state as it's too much hassle). A 270 works well on all 3. As a bonus, using your deer/bear gun on coyotes gives you more live target practice in the field. If you ever go antelope hunting, a 270 works great on them also. I step up in caliber for elk and moose but that's my personal preference and not meant as a slight on anybody else's choices. Which 270 are you considering?
