I would choose one of your 30 calibers. For strictly close range I would go with the 3006, but for longer shots I would go with one of the magnums. Factor the handling of the individual rifles to match the hunt also.

I usually carry my 350 mag, but also carry my 300 wsm or 3006. If I drive this year I will carry a 44 mag rifle which should also work well over bait. I cannot and do not hunt over bait though.
