Had a 7mm rem mag love it, got a 300 min mag love it too.....do you need it- no, but do you want it is what you wanna ask yourself. Personally i dont own a gun that dont let me know its there when i pull the trigger... if you want something to really put a lickin on a moose or elk look at the marlin 45 70 guide gun.. got one last year and didnt use anything else all season.
