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.
Mr. Barsness....
H4831sc has become unobtanium for me. RL-26 is hard to come by as well. I came across some RL-23 a few months back and would like to hear your experience with it. What kind of results did you get with it and 200 and/or 180 grainers in 30-06? Or overall what have you found with RL-23?
How about Hunter and 200grainers in 30-06.....I know you like 180's in 30-06 but what about 200 grainers?
