RE: best caliber rifle for white tails???
greg it depends upon the terrain and distances you will be hunting at. More white tail have been killed with a 30-30 than any other caliber. You can not go wrong with a 30-06, great knock down power and you can shoot them at a distance also.
Here is a suggestion, go down and check out the price of 30-30 & 30-06 ammo and then compare the cost to the other rounds out there. You can not get more bang for your buck than with a 30-30 or 30-06!
