The 300 H&H will do anything a 30-06 can and more. Does one need more? Hard to say, the 300 H&H is better with the heavier bullets. It may even be better than it's replacement the 300 WM at or above 200g. Mine is a pre-64 as well. Smoothest feeding rifle I have owned, accurate as in MOA or better with rounds it likes and will send a 180 at 3000fps or more. Not much not to like.
