I am late to this party.
My immediate thought before opening the thread was 338-06.
After reading the OP and scrolling through the posts., here are my thoughts.
Practical would be to keep it as is a 30-06 and make the package easier to carry. I struggle with tearing down a classic rifle though.
My choice would be a 338-06, I own three of them and would be my choice. Have taken an elk at 275yards with mine. If practiced, would not hesitate out to 450. I like 210's at 2800fps. Have blown through every elk I have shot with them.
I am not a 35 fan at all. Simple personal preference.
A 9.3x62 would be another good option.
