As mentioned, coyote hunting is rarely a volume of fire pursuit. You will most likely burn more rounds practicing then you will hunting. Which is as it should be. Think about it this way, odds are you won't shoot more then 20-40 rounds a year from a hunting gun. 22-250 will go 1500-2000 rounds before you won't have minute of coyote accuracy. So, somewhere between 50 and 100 years you'll have to put on another barrel. All this talk of burning out barrels has everyone paranoid. If you don't shoot competition or prairie dog/gopher towns, your barrel will outlive you. Relax and enjoy the time you have with your rifle in the field. - dan
