You might try 4831SC as well. I've gotten 2700 with it in 22" barrels when using 200 Partitions and Hodgdon's data, and in my present "main" .30-06 it's more accurate than RL-26.
While 26 is reasonably temperature-resistant, it wasn't designed to be like RL-16 and RL-23, and in my testing it hasn't been quite a consistent as the 16 and 23, or the Hodgdon Extremes, though it beats the hell out of some other powders.
