I am not a hunter,but this is my opinion. If you look in the various reloading manuals you'll find the biggest reloading section is for the 30'06. Jacketed bullets,lead bullets using rifle powders and pistol powders in every combination you can imagine. The various BELTED magnums gnerally burn 20% more powder to gain maybe 10% more velocity more recoil and a lot more muzzle blast. The '06 may not always be the best choice but under normal field use you can't go wrong.
