Alot depends on the type of coyote hunting you'll be doing. Spot and shoot, calling? Also the terrain you plan to hunt, eastside open country, thick sage or westside forest or clearcuts. For calling in tight cover I like a short fast handling rifle with a low power variable 1x4 or 1.5x6 or even a shotgun. For more open country a 24" barrelled sporter weight barrelled bolt action with a 2x10, 3x9. I have my favorite calibers but anything from 204 Ruger to 25-06 will do the trick.
