Well, from your description of the components you've tried, I would think I had just begun the search. There are lots more bullets, powder, case and primer combinations to try, not to mention a systematic effort to test overall lengths. There are many variables you haven't even mentioned like neck sizing, weighing cases, turning necks, and so on to keep you occupied for a while too.
One comment/question. Is the 3.8 inch groups from your other rifles correct? If that is the best you have shot with an -06 or the .338, your bench rest technique may be another variable to examine. I have never seen a rifle in those calibers that would not shoot better than that. Mind you, I have personal experience with only two .338's, but several -06's
In short, you have just begun the search for accuracy. If you want another gun, sell the one you have, but the next one may take just as much effort to find a load that will shoot less than 1 moa. Such rifle/load combinations are more rare than you would think if you just listened to writers in magazines and the stories around hunting camps.
