RE: Coyote bullets for .243 ?
My favorite, where I'm just exterminating them and not overly concerned about exit hole, is the 70 gr. Nosler Ballistic Tip. The 55 gr. Ballistic Tip shoots a little flatter but seems a bit more fickle - at least in the three rifles I have used with this bullet. For minimum damage to pelts, you might consider the Barnes X bullet. It will always exit, and leave a finger size hole - unless you hit big bone, of course.
