Looking for a new powder 26 nosler

[6.5x300 WBY]

The most temp stable powders are the Hodgdon powders Varget, H1000, H4895, H4350, H4831, and only a few others that are under .5fps change in temp per degree. in a 130 degree change in weather it amount to about 20fps differece between high and low velocity using the means of the temp range. 30FPS SD@ 1000yds is 8.5" and 50fps variation is about 14" @ 1000yds. So now if you are using other powders that the temp changes 1 degree equals 1fps change in vleocity. Take the means of that would be 65fps between high and low temp. There is a lot of powders that change up to 1.5 and more fps per degree. So go ahead figure out what you need
I wish that there was more on temp changes on powder than what it out there presently. A lot of the reloader powder is over 1.2 fps deviation or (SD) change per degree.
It's my understanding that there is programs out there that can take all that info in and give you a shooting solution. I have the programs but I haven't use them yet.
So depending on the yardages you are shooting at there some figuring to do.

Which of the two would be the least temp sensitive?
Is Rl 33 pretty sensitive?
The RL 16 that I use is not

I burn ALOT of those two powders with several calibers from 6.5 up to .338 in +/-70°F temp deltas (20°F - 90°F) and are flawless performers for me.

I would give LRT a go. I just picked some up to try.
I run rl33 behind a 127lrx in mine, shoots that very well but its not temp stable.

LRT has been a great powder for pushing a 215 Hybrid in my 300 NMI.

Looking at that sinsitivity chart I may need to change powerder in a couple of my other loads.
Like my 7 RUM that I am running 7828 in and a couple that we run IMR 4931 in

Just a guide as I never trust printed results. I trust first hand results that you try. Come across too many times where this chart didn't match my results. So alway look at it as a guide but test yourself.

They are both very stable, the only thing I have witnessed was that Retumbo in some very cold weather was difficult to ignite. I don't believe this has anything to do with it's temp stability, however.
I have used kegs of H50BMG without a single issue, however, all of my cases using it are from about 112g-150g capacity, I believe this makes a difference in case pressure and ignition.
Yes, in my experience, RE33 gets touchy around 100° F, and also in the cold. I wish I could still get US869 here, very useful powder and is touchy, but not like RE33.
ADI Extreme powder list includes Retumbo and H50BMG, it is made here in Australia, it has different designation, but is simply the same powder re-branded by Hodgdon.

Cheers.

I have 869 but there is a 3 inch difference in poi. From summer to winter so I am trying to change powder to get a better consistent results. So I am going to try retumbo because I can get it locally

I can't quite get all of the picture to open up. I do see some Vihtavuori powders at the bottom, that I don't have listing on. Please advise.
Thanks,

I wanna get my hands on some ramshot LRT sometime for overbore cartridges. It sounds perfect, but I can't find it yet.

Inyou photo of the stability chart what does the "Hornady 4DOF" stand for?
Every chart I have been able to fi d does not show any info on RL33 except under 4DOF collum
Thanks
