If it is legal to hunt with a center fire rifle I would go with the 06. you can shoot at longer ranges, ammo is easy to find and it has far less recoil. I have seen people at the rifle range and the cannnot get there slug guns sighted in properly because of the recoil. I have a Sauer 30.06 and an A5 with a rifled barrel and the A5 has twice has much recoil has my Sauer.
