28 Nosler RL33 or Retumbo

[Aking]

I am loading 175grain Accubond Long Range in a 1-9 twist 26" barrel. I have zero expertise with either powder. I have heard RL 33 can be temp sensitive and was looking for some input. As for Retumbo The load data on Nosler says it is slightly slower, but I will take accuracy over speed. Which is the better powder, if where I hunt is 30-80 degrees throughout October in South Eastern Idaho?

Of those two I had better luck with retumbo and 175 gr. But H1000 shot the best of all the powders I tried

Use retumbo with those 175's.
