I put a 17 Remington barrel on an AR15 for a guy when I worked in a gunshop in AK. He was from SE AK and said he’d worn out a Rem700 in the same chambering and was going to the AR as it had been given to him. He claimed to have killed dozens of deer with his old 700, as well as plenty of wolves and countless foxes. I know another guy who killed 18 wolves and 8 caribou with a 700 in 17Rem. I don’t think you’ll have any problem killing coyotes with one if you stick to the 25gr Hornady, I don’t with mine anyway.
