if you have wolves around the 17 rem. is to light for consistent kills.I believe the 25 gr.blows up before it gets through the second lung.I have seen 2 perfect behind the shoulder lung hits at 60 and 80 yards bleeding good but just kept going.Any coyote with that hit out to 300 yards is DRT no fur damage.So if wolves are a possibility go with a 50 plus gr. my favorite a 222 but 223 would be the ticket.A 243 is hard to beat and if you reload can be very fur friendly.
