are you all kidding a .308 will stop a bear in its tracks. you all think you need some big cannon. 30-06 may be fine but if you really want to get to the nitty gritty a 30-06 looses its balls where as a .308 is a straight out blaster. maybe ya all need a bazooka. shoot ill take a bear with my rem 12ga if you cant take a bear with a .308 then there is only one problem... the shooter. its shot placement that takes the game. not how big your cannon is. if you feel you need a cannon then you know your shot is less than accurate and need the extra powder to make up for lousy shooting. just my 2 cents here.....
