Your 30-06 oppinin would be a fine choice for deer, bear, moose. I wouldnt reccomend starting with anything smaller than the .308. Tuk101's suggestions seemed pretty reasonable to me. I dont suggest the 7mm-08 for bear or moose although good bullet placement would sure enough put one down, i would suggest either your 30-06, 7mm Mag, 300 mag, or even the 308. If your looking for a manufacture for your rifle, im not sure its possible to beat savage for their money,
