My best loads for my 338-06:
200gr Accubond or Ballistic Silvertip
Win Case,WLRM Primer
59.0grs of Big Game or 59.0grs of CFE223
These run a tad over 2800fps out of my rifle
210 Partition
Win Case,WLRM Primer
54.0grs Varget
This load runs a little over 2700fps out of my rifle
Really,I found the 338-06 to be easy to load for.With the 200gr bullets,I think any powder between say Varget to 4350 will give you an acceptable load.
59.0grs Big Game 2812fps
59.0grs CFE223 2807fps
54.0gr Varget 2721fps
