If I go East for coyotes, and plan to save pelts, I take my 17 Remington. They go ker-flop, and have an itty bitty entrance hole and never an exit. That little pill just explodes inside. They do have a limited range though...makes you a better caller to get them closer.
There is a couple things I don't like about the 17 Rem though; if you have big paws...reloading sucks! Also, brass is hard to find. I had a really good shooting upper on an AR, and sold it because I hate brass catchers on a calling rifle, and so I lost more brass than I found.
Love all the 17's for Sage Rats!
