If I were hunting coyotes along with deer with one rifle I’d probably go .243. For deer only it would probably be 6.5 Creedmoor. I don’t believe the .308 kills deer any better than a 6.5 Creedmoor at any distance. Under 300 yards I don’t believe there is much difference between a 6.5 Creedmoor and .243. Past 300 yards I do think a Creedmoor is probably better.
