Some people say its temp sensitive I have used it but I havent tested its temp sensitive. Here in Montana during hunting season we dont get big swings and I try to do load development in my hunting rifles close to those temps and it probably wont be any different than the 4831 your using now.
The new RL powders produce good velocity and accuracy.
RL-26 is temp sensitive?
And what snowflake would name their kid "Some people"......?
Have either of you used it in the 300 WSM?
Of course not--Alliant has no pressure data for 300 WSM. When I spoke to CS at Alliant he told me RL-26 is a powder for fairly specific applications. The cartridges--and the bullet weights--they chose were within the optimum energy and burn rate they thought RL-26 was best suited for. Powders aren't just about burn rates, there is also differing energy that accompanies the burn rate.
If a guy wants to take the time to look at the list of cartridges Alliant did chose to pressure test, only a few of them show significant increases in velocity over other powders. The 270 with 150 grain bullets appears to be the big winner. Maybe as time goes on and the bullet manufacturers jump onboard there will be more data for other cartridges that does indeed show better velocity.
Rifle loonys being somewhat loony.....of course everybody saw Muledeer's post on the 270 and 150gr bullets, and figured their fav cartridge should see the same kind of wonderous increase in velocities. When there is no pressure data it becomes easy to rationalize any velocity that doesn't blow the primer plumb out of the case. We can be assured a lot of velocities being posted on the internet using RL-26 in cartridges with no pressure tested data will ultimately be demonstrated to be hot--very hot.
It wasn't that long ago that the same thing was happening with RL-22. And take a new powder like RL-26 with a new cartridge like the 6.5 CM and the sky is the limit here in Loonydom.......
Of course my post ain't gonna change any minds, so my question to you is; What is going to be your starting load of RL-26?......
