I can't find much data. Anyone have any luck with this combo?
I've never tried R26 but there's a couple threads in the bullet test section on the Nosler forums where someone has used R26 with a couple different bullets. You may have to go through the list and open the thread because it may not be in the title.

Haven't used R26. I personally have good luck with imr4350 in all my 1/4 bores with 100gr and up projectiles. Load a box up and give it a try.
tried RL26 with the 110 grn ELDX. Good velocity but accuracy just ok. I've had excellent results with Retumbo for 110 - 117 grain bullets. I get tiny groups with the 110 Accubond at 3175 fps with Retumbo.
My wife's Tikka 25-06 loves RL-22 with 117 or 115 Nosler Ballistic Tips. Not sure of MV but it is not a slouch and 3/4 inch groups. Don't remember the load.
If you do not get good groups with 26, change primers several times. Get ready for a shock.
I tried 26 with 115 NBT worked well limited tests. PM for data
As I recall, the data I’ve seen for RL26 didn’t match up very well velocity-wise with the old RL22 recipe I have, and which shoots very well in my rifle . But I haven’t tried RL26 in a 25-06 either.
Kinda the same with 7mm RM.
I finally got speed out of my 7 mag once I tried RL26. Couldn’t break 3000 FPS with RL22. Was just under 3200 with 26.

Ended up using 150 TTSX,
tried 150 sciroccos, nos 150 bt. Struggled with reloads getting any kind of speed or groups. but Could get the factory 150 core lokts to run the advertised 3100 and group. Finally tried RL 26 and the 150 TTSX with 67 gr .080 off the lands worked. I want to try some heavier bullets soon as the weather breaks.
I think I am at 59.5 with the Hornaday 117s this may be too hot but my 25-06 has a long throat. Have not run them over the chrono yet. I would just run them up to 3,200 fps and stop there. Quickload has the wrong burn rate for R26 so be careful using that data.
