Ther is lots of info out there for you to research. I hunt coyotes here in the south and used my .280 for a long time untill i got a 22-250. I generally go out late at night and howl at my hunting grounds. If no response i will usually not hunt that location in the morning. I prefer to hunt cross wind with clear and long view down wind. I have been busted by circling coyotes winding me with wind in the face
