The ballistics of the 30-06 are better than a 30-30. For example using certain loads a 30-30 would give you a maximim of about 1900 pounds of muzzele energy. The 30-06 on the otherhand might give you up to 3000 pounds of muzzle energy depending on loads used. The 30-06 also has a straighter tragectory than the 30-30. In my opinion a 30-30 is good for deer and adequate for anything up to a black bear(NOT GRIZZLIES) but a 30-06 is far superior for any bear. As far as wanting a lever-action versus a bolt or automatic that is a matter of personal preference. Im not sure who or if anyone makes a lever-action 30-06. If you want a lever action thats capable for any North American game and has several loadings available try a Marlin 45-70 lever-action. Has a bit of recoil though. By the way after wanting a lever gun for decades my sweet loving wife of 37 years finally bought me one 2 years ago. Its a Henry 22lr and is a blast (no pun intended) to shoot.
