I am planning on using it in my 6.5 Creedmoor build. I have some H4350, Norma MRP, Norma URP, H205 and some of the RL26 I just got a hold of. From what I have read about it and from what QL shows it seems to be promising in the Creedmoor.

Experimented with first load, 80.00 grains RL-26 , WW Case, F-215 Primers, 300 Win Mag with 168 grain BArnes Triple Shock, grouped nice, never chronoed the load but no pressure signs.

300Rum
87 grains RL 26
Remington Brass
220 ELD-X
3.65 seated in mag of my factory 300RUM and still able to cycle
1 inch group a 200yrds
Shot deer at 761 yrds with 10 MOA dial up.
was shooting at 1678 with 46 MOA but was dancing around about 1.5MOA around target. Still need to calculate velocity out to be exact and dial the load a little better.
Cheap chrono is posting 3020 but I think the load is shooting faster according to my shooter ap.
SD was 7.

I've been impressed with RL-26. It appears to be the top performer in a bunch of rifles that are more popular than those for which RL-33 would be the best choice. It is also nice that Alliant paid some attention to temp drift (which is horrible in their RL-22 and RL-25) and made this one moderately stable - good enough to live with.

Agreed the temp stability of RL -22 was not good at all, really noticed it up here in Alberta. I am just hoping I can utilize RL-23 in my 2 30-06 rifles and maintain the performance of the cartridge.

How would you compare RL26 stability hodgdens extreme powders, namely H4831sc? I shoot more fclass rounds than I do hunting rounds and temps here can jump pretty quickly sometimes hitting 90's before our match is over.

Per QuickLoad, the burn rate of RL-22 is 0.3860 and it is 0.4090 for RL-23. So RL-23 should perform reasonably well if not great in a 30-06 sized cases not to mention the supposed rock solid stability over temperature.

RL-26 has a published drift rate of 0.5 fps per degree F. Alliant characterizes this as "moderate". Hodgdon says their Extreme powders are "stable". I don't have any numbers for Hodgdon powders but my experience indicates that the are in the area of twice as stable as the RL-17/RL-26/RL-33/RL-50 family of powders made for Alliant by Nitrochemie. Were I you however I would give RL-23 a try as it is made for Alliant by Bofors in Sweeden an along with RL-16 is supposed to be as stable as you can get. It is a little slower powder than H4831 which might work out very well for you.

Thanks, I love RL-22 but I reload all summer and then when fall and winter hits Ive gone from Plus 75 to 80 F to 20-30 below zero. This really affects things. For how far I plan to shoot with my 300 mags 0.5 fps per degree is minimal lol and may just require a couple of shots in the cold weather to confirm zero.
I tested R26 a few weeks ago. I found 2 fps per degree with a 25 degree temperature change. From 54 to 25 degrees I lost 58 fps.
No bueno!
RL 26 has become my new favorite 300 Rum load. I was warned about possible temp swings. Figured I would zero the gun in at 35 degrees or so and then shoot it at different temperatures to see what it looked like on paper and compensate accordingly if the need ever arose...

In my .260 ackley I got the 147 eld-m up to 3092 fps, without any observed pressure signs. I'm in the process of playing with it more, but it seemed the most promising load was 3040 fps, still in the realm of a 6.5 SAUM with a 147 grain bullet. I'm very happy with it.
I'm going to check temp stability as well, as these velocities were shot @ 20 degrees F.

I would like to see more info on this, everyone else I have talked to had seen between .3 and .5 fps per degree. Were you using an optical chrono? was anything different with your loads? Info like this is needed to make much use of data statements
Cartridge, bullet, charge weight, primer etc ?
