I have "many" rifles…
But have never even owned a 30-06..
If I had owned one i wouldn't need another big game rifle.
I'll never own one!

There you go again- using logic!!
I've owned a half dozen .30-06 and only one .338WM. Stillll own two and one, respectively. Haven't shot an elk with any of them - just a bunch of other stuff from one mule deer to probably 15ish moose and a couple dozen caribou between them.
Can't tell any difference. None of the moose were over 160 yards, and only 2 over 100.
Some of the caribou were over 300, and one over 400- all those with an .06, but the .338 would have done it. One just needs to know trajectory. And have a good rest.
The only elk I've shot was with a .260 at 150 yards. Bang flop.
So it is my considered opinion I'm just no danged help to the OP at all!
But if that 06 shoots well, leave it alone. Don't fix what ain't broke.
Of course, then he has to get that .338-06.....
