Well it can't be a predator rifle unless it has predator, coyote, dog slayer etc. In the name of the gun. And it has to have a special optic with said names on them that the manufacturers have so nicely labeled them with so we know what to use. Of course they have to have the newest special camo pattern that matches all our gear. Otherwise you'll never get a coyote. The only exception is if you have seen the experts on tv use them because then they are an acceptable option and just haven't had the proper naming applied yet.
