RL15, RL16, RL23, RL26, RL33 are temp stable
I use RL23 and 26 in my 280 with good results. I have Viht n560 and 565 but haven't used them much yet
RL16 would be good in 30-06
In my testing, I have found the following averages for temp shifts from -15c to +29c
Hodgdon extreme powders - 19 fps
Alliant stable powders - 20 fps
IMR Enduron powders - 41 fps
Regular sensitive powders (RL22, IMR 4831 etc) 83 fps
Ball powders (Win 748, Win 760, H414) 90 fps
Most of the variation is from +13c to +29c. Not as much difference from +13c to -15c
