I'm looking into purchasing my first bolt action(besides my .22lr). I want to use it as a defensive gun to immobilize vehicles that try to come onto my land in a shtf situation also a using as a hunting rifle also. I have about a $500 dollar limit to spend on the gun and a scope. I would like to be able to shoot to about 300 yards. i just don't know what caliber to get. I would prefer that it have had a 5 round magazine if possible.
